+// Package cmp determines equality of values.
+//
+// This package is intended to be a more powerful and safer alternative to
+// reflect.DeepEqual for comparing whether two values are semantically equal.
+//
+// The primary features of cmp are:
+//
+// • When the default behavior of equality does not suit the needs of the test,
+// custom equality functions can override the equality operation.
+// For example, an equality function may report floats as equal so long as they
+// are within some tolerance of each other.
+//
+// • Types that have an Equal method may use that method to determine equality.
+// This allows package authors to determine the equality operation for the types
+// that they define.
+//
+// • If no custom equality functions are used and no Equal method is defined,
+// equality is determined by recursively comparing the primitive kinds on both
+// values, much like reflect.DeepEqual. Unlike reflect.DeepEqual, unexported
+// fields are not compared by default; they result in panics unless suppressed
+// by using an Ignore option (see cmpopts.IgnoreUnexported) or explicitly compared
+// using the AllowUnexported option.

+// Equal reports whether x and y are equal by recursively applying the
+// following rules in the given order to x and y and all of their sub-values:
+//
+// • If two values are not of the same type, then they are never equal
+// and the overall result is false.
+//
+// • Let S be the set of all Ignore, Transformer, and Comparer options that
+// remain after applying all path filters, value filters, and type filters.
+// If at least one Ignore exists in S, then the comparison is ignored.
+// If the number of Transformer and Comparer options in S is greater than one,
+// then Equal panics because it is ambiguous which option to use.
+// If S contains a single Transformer, then use that to transform the current
+// values and recursively call Equal on the output values.
+// If S contains a single Comparer, then use that to compare the current values.
+// Otherwise, evaluation proceeds to the next rule.
+//
+// • If the values have an Equal method of the form "(T) Equal(T) bool" or
+// "(T) Equal(I) bool" where T is assignable to I, then use the result of
+// x.Equal(y) even if x or y is nil.
+// Otherwise, no such method exists and evaluation proceeds to the next rule.
+//
+// • Lastly, try to compare x and y based on their basic kinds.
+// Simple kinds like booleans, integers, floats, complex numbers, strings, and
+// channels are compared using the equivalent of the == operator in Go.
+// Functions are only equal if they are both nil, otherwise they are unequal.
+// Pointers are equal if the underlying values they point to are also equal.
+// Interfaces are equal if their underlying concrete values are also equal.
+//
+// Structs are equal if all of their fields are equal. If a struct contains
+// unexported fields, Equal panics unless the AllowUnexported option is used or
+// an Ignore option (e.g., cmpopts.IgnoreUnexported) ignores that field.
+//
+// Arrays, slices, and maps are equal if they are both nil or both non-nil
+// with the same length and the elements at each index or key are equal.
+// Note that a non-nil empty slice and a nil slice are not equal.
+// To equate empty slices and maps, consider using cmpopts.EquateEmpty.

+	//	• Searching for differences switches back-and-forth between
+	//	a search that starts at the beginning (the top-left corner), and
+	//	a search that starts at the end (the bottom-right corner). The goal of
+	//	the search is connect with the search from the opposite corner.
+	//	• As we search, we build a path in a greedy manner, where the first
+	//	match seen is added to the path (this is sub-optimal, but provides a
+	//	decent result in practice). When matches are found, we try the next pair
+	//	of symbols in the lists and follow all matches as far as possible.
+	//	• When searching for matches, we search along a diagonal going through
+	//	through the "frontier" point. If no matches are found, we advance the
+	//	frontier towards the opposite corner.
+	//	• This algorithm terminates when either the X coordinates or the
+	//	Y coordinates of the forward and reverse frontier points ever intersect.
+	//
+	// This algorithm is correct even if searching only in the forward direction
+	// or in the reverse direction. We do both because it is commonly observed
+	// that two lists commonly differ because elements were added to the front
+	// or end of the other list.

+Contributing To gopacket
+========================
+
+So you've got some code and you'd like it to be part of gopacket... wonderful!
+We're happy to accept contributions, whether they're fixes to old protocols, new
+protocols entirely, or anything else you think would improve the gopacket
+library.  This document is designed to help you to do just that.
+
+The first section deals with the plumbing:  how to actually get a change
+submitted.
+
+The second section deals with coding style... Go is great in that it
+has a uniform style implemented by 'go fmt', but there's still some decisions
+we've made that go above and beyond, and if you follow them, they won't come up
+in your code review.
+
+The third section deals with some of the implementation decisions we've made,
+which may help you to understand the current code and which we may ask you to
+conform to (or provide compelling reasons for ignoring).
+
+Overall, we hope this document will help you to understand our system and write
+great code which fits in, and help us to turn around on your code review quickly
+so the code can make it into the master branch as quickly as possible.
+
+
+How To Submit Code
+------------------
+
+We use github.com's Pull Request feature to receive code contributions from
+external contributors.  See
+https://help.github.com/articles/creating-a-pull-request/ for details on
+how to create a request.
+
+Also, there's a local script `gc` in the base directory of GoPacket that
+runs a local set of checks, which should give you relatively high confidence
+that your pull won't fail github pull checks.
+
+```sh
+go get github.com/google/gopacket
+cd $GOROOT/src/pkg/github.com/google/gopacket
+git checkout -b <mynewfeature>  # create a new branch to work from
+... code code code ...
+./gc  # Run this to do local commits, it performs a number of checks
+```
+
+To sum up:
+
+* DO
+    + Pull down the latest version.
+    + Make a feature-specific branch.
+    + Code using the style and methods discussed in the rest of this document.
+    + Use the ./gc command to do local commits or check correctness.
+    + Push your new feature branch up to github.com, as a pull request.
+    + Handle comments and requests from reviewers, pushing new commits up to
+      your feature branch as problems are addressed.
+    + Put interesting comments and discussions into commit comments.
+* DON'T
+    + Push to someone else's branch without their permission.
+
+
+Coding Style
+------------
+
+* Go code must be run through `go fmt`, `go vet`, and `golint`
+* Follow http://golang.org/doc/effective_go.html as much as possible.
+    + In particular, http://golang.org/doc/effective_go.html#mixed-caps.  Enums
+      should be be CamelCase, with acronyms capitalized (TCPSourcePort, vs.
+      TcpSourcePort or TCP_SOURCE_PORT).
+* Bonus points for giving enum types a String() field.
+* Any exported types or functions should have commentary
+  (http://golang.org/doc/effective_go.html#commentary)
+
+
+Coding Methods And Implementation Notes
+---------------------------------------
+
+### Error Handling
+
+Many times, you'll be decoding a protocol and run across something bad, a packet
+corruption or the like.  How do you handle this?  First off, ALWAYS report the
+error.  You can do this either by returning the error from the decode() function
+(most common), or if you're up for it you can implement and add an ErrorLayer
+through the packet builder (the first method is a simple shortcut that does
+exactly this, then stops any future decoding).
+
+Often, you'll already have decode some part of your protocol by the time you hit
+your error.  Use your own discretion to determine whether the stuff you've
+already decoded should be returned to the caller or not:
+
+```go
+func decodeMyProtocol(data []byte, p gopacket.PacketBuilder) error {
+  prot := &MyProtocol{}
+  if len(data) < 10 {
+    // This error occurred before we did ANYTHING, so there's nothing in my
+    // protocol that the caller could possibly want.  Just return the error.
+    return fmt.Errorf("Length %d less than 10", len(data))
+  }
+  prot.ImportantField1 = data[:5]
+  prot.ImportantField2 = data[5:10]
+  // At this point, we've already got enough information in 'prot' to
+  // warrant returning it to the caller, so we'll add it now.
+  p.AddLayer(prot)
+  if len(data) < 15 {
+    // We encountered an error later in the packet, but the caller already
+    // has the important info we've gleaned so far.
+    return fmt.Errorf("Length %d less than 15", len(data))
+  }
+  prot.ImportantField3 = data[10:15]
+  return nil  // We've already added the layer, we can just return success.
+}
+```
+
+In general, our code follows the approach of returning the first error it
+encounters.  In general, we don't trust any bytes after the first error we see.
+
+### What Is A Layer?
+
+The definition of a layer is up to the discretion of the coder.  It should be
+something important enough that it's actually useful to the caller (IE: every
+TLV value should probably NOT be a layer).  However, it can be more granular
+than a single protocol... IPv6 and SCTP both implement many layers to handle the
+various parts of the protocol.  Use your best judgement, and prepare to defend
+your decisions during code review. ;)
+
+### Performance
+
+We strive to make gopacket as fast as possible while still providing lots of
+features.  In general, this means:
+
+* Focus performance tuning on common protocols (IP4/6, TCP, etc), and optimize
+  others on an as-needed basis (tons of MPLS on your network?  Time to optimize
+  MPLS!)
+* Use fast operations.  See the toplevel benchmark_test for benchmarks of some
+  of Go's underlying features and types.
+* Test your performance changes!  You should use the ./gc script's --benchmark
+  flag to submit any performance-related changes.  Use pcap/gopacket_benchmark
+  to test your change against a PCAP file based on your traffic patterns.
+* Don't be TOO hacky.  Sometimes, removing an unused struct from a field causes
+  a huge performance hit, due to the way that Go currently handles its segmented
+  stack... don't be afraid to clean it up anyway.  We'll trust the Go compiler
+  to get good enough over time to handle this.  Also, this type of
+  compiler-specific optimization is very fragile; someone adding a field to an
+  entirely different struct elsewhere in the codebase could reverse any gains
+  you might achieve by aligning your allocations.
+* Try to minimize memory allocations.  If possible, use []byte to reference
+  pieces of the input, instead of using string, which requires copying the bytes
+  into a new memory allocation.
+* Think hard about what should be evaluated lazily vs. not.  In general, a
+  layer's struct should almost exactly mirror the layer's frame.  Anything
+  that's more interesting should be a function.  This may not always be
+  possible, but it's a good rule of thumb.
+* Don't fear micro-optimizations.  With the above in mind, we welcome
+  micro-optimizations that we think will have positive/neutral impacts on the
+  majority of workloads.  A prime example of this is pre-allocating certain
+  structs within a larger one:
+
+```go
+type MyProtocol struct {
+  // Most packets have 1-4 of VeryCommon, so we preallocate it here.
+  initialAllocation [4]uint32
+  VeryCommon []uint32
+}
+
+func decodeMyProtocol(data []byte, p gopacket.PacketBuilder) error {
+  prot := &MyProtocol{}
+  prot.VeryCommon = proto.initialAllocation[:0]
+  for len(data) > 4 {
+    field := binary.BigEndian.Uint32(data[:4])
+    data = data[4:]
+    // Since we're using the underlying initialAllocation, we won't need to
+    // allocate new memory for the following append unless we more than 16
+    // bytes of data, which should be the uncommon case.
+    prot.VeryCommon = append(prot.VeryCommon, field)
+  }
+  p.AddLayer(prot)
+  if len(data) > 0 {
+    return fmt.Errorf("MyProtocol packet has %d bytes left after decoding", len(data))
+  }
+  return nil
+}
+```
+
+### Slices And Data
+
+If you're pulling a slice from the data you're decoding, don't copy it.  Just
+use the slice itself.
+
+```go
+type MyProtocol struct {
+  A, B net.IP
+}
+func decodeMyProtocol(data []byte, p gopacket.PacketBuilder) error {
+  p.AddLayer(&MyProtocol{
+    A: data[:4],
+    B: data[4:8],
+  })
+  return nil
+}
+```
+
+The caller has already agreed, by using this library, that they won't modify the
+set of bytes they pass in to the decoder, or the library has already copied the
+set of bytes to a read-only location.  See DecodeOptions.NoCopy for more
+information.
+
+### Enums/Types
+
+If a protocol has an integer field (uint8, uint16, etc) with a couple of known
+values that mean something special, make it a type.  This allows us to do really
+nice things like adding a String() function to them, so we can more easily
+display those to users.  Check out layers/enums.go for one example, as well as
+layers/icmp.go for layer-specific enums.
+
+When naming things, try for descriptiveness over suscinctness.  For example,
+choose DNSResponseRecord over DNSRR.

+Package gopacket provides packet decoding for the Go language.
+
+gopacket contains many sub-packages with additional functionality you may find
+useful, including:
+
+ * layers: You'll probably use this every time.  This contains of the logic
+     built into gopacket for decoding packet protocols.  Note that all example
+     code below assumes that you have imported both gopacket and
+     gopacket/layers.
+ * pcap: C bindings to use libpcap to read packets off the wire.
+ * pfring: C bindings to use PF_RING to read packets off the wire.
+ * afpacket: C bindings for Linux's AF_PACKET to read packets off the wire.
+ * tcpassembly: TCP stream reassembly
+
+Also, if you're looking to dive right into code, see the examples subdirectory
+for numerous simple binaries built using gopacket libraries.
+
+Minimum go version required is 1.5 except for pcapgo/EthernetHandle, afpacket,
+and bsdbpf which need at least 1.7 due to x/sys/unix dependencies.
+
+Basic Usage
+
+gopacket takes in packet data as a []byte and decodes it into a packet with
+a non-zero number of "layers".  Each layer corresponds to a protocol
+within the bytes.  Once a packet has been decoded, the layers of the packet
+can be requested from the packet.
+
+ // Decode a packet
+ packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Default)
+ // Get the TCP layer from this packet
+ if tcpLayer := packet.Layer(layers.LayerTypeTCP); tcpLayer != nil {
+   fmt.Println("This is a TCP packet!")
+   // Get actual TCP data from this layer
+   tcp, _ := tcpLayer.(*layers.TCP)
+   fmt.Printf("From src port %d to dst port %d\n", tcp.SrcPort, tcp.DstPort)
+ }
+ // Iterate over all layers, printing out each layer type
+ for _, layer := range packet.Layers() {
+   fmt.Println("PACKET LAYER:", layer.LayerType())
+ }
+
+Packets can be decoded from a number of starting points.  Many of our base
+types implement Decoder, which allow us to decode packets for which
+we don't have full data.
+
+ // Decode an ethernet packet
+ ethP := gopacket.NewPacket(p1, layers.LayerTypeEthernet, gopacket.Default)
+ // Decode an IPv6 header and everything it contains
+ ipP := gopacket.NewPacket(p2, layers.LayerTypeIPv6, gopacket.Default)
+ // Decode a TCP header and its payload
+ tcpP := gopacket.NewPacket(p3, layers.LayerTypeTCP, gopacket.Default)
+
+
+Reading Packets From A Source
+
+Most of the time, you won't just have a []byte of packet data lying around.
+Instead, you'll want to read packets in from somewhere (file, interface, etc)
+and process them.  To do that, you'll want to build a PacketSource.
+
+First, you'll need to construct an object that implements the PacketDataSource
+interface.  There are implementations of this interface bundled with gopacket
+in the gopacket/pcap and gopacket/pfring subpackages... see their documentation
+for more information on their usage.  Once you have a PacketDataSource, you can
+pass it into NewPacketSource, along with a Decoder of your choice, to create
+a PacketSource.
+
+Once you have a PacketSource, you can read packets from it in multiple ways.
+See the docs for PacketSource for more details.  The easiest method is the
+Packets function, which returns a channel, then asynchronously writes new
+packets into that channel, closing the channel if the packetSource hits an
+end-of-file.
+
+  packetSource := ...  // construct using pcap or pfring
+  for packet := range packetSource.Packets() {
+    handlePacket(packet)  // do something with each packet
+  }
+
+You can change the decoding options of the packetSource by setting fields in
+packetSource.DecodeOptions... see the following sections for more details.
+
+
+Lazy Decoding
+
+gopacket optionally decodes packet data lazily, meaning it
+only decodes a packet layer when it needs to handle a function call.
+
+ // Create a packet, but don't actually decode anything yet
+ packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
+ // Now, decode the packet up to the first IPv4 layer found but no further.
+ // If no IPv4 layer was found, the whole packet will be decoded looking for
+ // it.
+ ip4 := packet.Layer(layers.LayerTypeIPv4)
+ // Decode all layers and return them.  The layers up to the first IPv4 layer
+ // are already decoded, and will not require decoding a second time.
+ layers := packet.Layers()
+
+Lazily-decoded packets are not concurrency-safe.  Since layers have not all been
+decoded, each call to Layer() or Layers() has the potential to mutate the packet
+in order to decode the next layer.  If a packet is used
+in multiple goroutines concurrently, don't use gopacket.Lazy.  Then gopacket
+will decode the packet fully, and all future function calls won't mutate the
+object.
+
+
+NoCopy Decoding
+
+By default, gopacket will copy the slice passed to NewPacket and store the
+copy within the packet, so future mutations to the bytes underlying the slice
+don't affect the packet and its layers.  If you can guarantee that the
+underlying slice bytes won't be changed, you can use NoCopy to tell
+gopacket.NewPacket, and it'll use the passed-in slice itself.
+
+ // This channel returns new byte slices, each of which points to a new
+ // memory location that's guaranteed immutable for the duration of the
+ // packet.
+ for data := range myByteSliceChannel {
+   p := gopacket.NewPacket(data, layers.LayerTypeEthernet, gopacket.NoCopy)
+   doSomethingWithPacket(p)
+ }
+
+The fastest method of decoding is to use both Lazy and NoCopy, but note from
+the many caveats above that for some implementations either or both may be
+dangerous.
+
+
+Pointers To Known Layers
+
+During decoding, certain layers are stored in the packet as well-known
+layer types.  For example, IPv4 and IPv6 are both considered NetworkLayer
+layers, while TCP and UDP are both TransportLayer layers.  We support 4
+layers, corresponding to the 4 layers of the TCP/IP layering scheme (roughly
+anagalous to layers 2, 3, 4, and 7 of the OSI model).  To access these,
+you can use the packet.LinkLayer, packet.NetworkLayer,
+packet.TransportLayer, and packet.ApplicationLayer functions.  Each of
+these functions returns a corresponding interface
+(gopacket.{Link,Network,Transport,Application}Layer).  The first three
+provide methods for getting src/dst addresses for that particular layer,
+while the final layer provides a Payload function to get payload data.
+This is helpful, for example, to get payloads for all packets regardless
+of their underlying data type:
+
+ // Get packets from some source
+ for packet := range someSource {
+   if app := packet.ApplicationLayer(); app != nil {
+     if strings.Contains(string(app.Payload()), "magic string") {
+       fmt.Println("Found magic string in a packet!")
+     }
+   }
+ }
+
+A particularly useful layer is ErrorLayer, which is set whenever there's
+an error parsing part of the packet.
+
+ packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Default)
+ if err := packet.ErrorLayer(); err != nil {
+   fmt.Println("Error decoding some part of the packet:", err)
+ }
+
+Note that we don't return an error from NewPacket because we may have decoded
+a number of layers successfully before running into our erroneous layer.  You
+may still be able to get your Ethernet and IPv4 layers correctly, even if
+your TCP layer is malformed.
+
+
+Flow And Endpoint
+
+gopacket has two useful objects, Flow and Endpoint, for communicating in a protocol
+independent manner the fact that a packet is coming from A and going to B.
+The general layer types LinkLayer, NetworkLayer, and TransportLayer all provide
+methods for extracting their flow information, without worrying about the type
+of the underlying Layer.
+
+A Flow is a simple object made up of a set of two Endpoints, one source and one
+destination.  It details the sender and receiver of the Layer of the Packet.
+
+An Endpoint is a hashable representation of a source or destination.  For
+example, for LayerTypeIPv4, an Endpoint contains the IP address bytes for a v4
+IP packet.  A Flow can be broken into Endpoints, and Endpoints can be combined
+into Flows:
+
+ packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
+ netFlow := packet.NetworkLayer().NetworkFlow()
+ src, dst := netFlow.Endpoints()
+ reverseFlow := gopacket.NewFlow(dst, src)
+
+Both Endpoint and Flow objects can be used as map keys, and the equality
+operator can compare them, so you can easily group together all packets
+based on endpoint criteria:
+
+ flows := map[gopacket.Endpoint]chan gopacket.Packet
+ packet := gopacket.NewPacket(myPacketData, layers.LayerTypeEthernet, gopacket.Lazy)
+ // Send all TCP packets to channels based on their destination port.
+ if tcp := packet.Layer(layers.LayerTypeTCP); tcp != nil {
+   flows[tcp.TransportFlow().Dst()] <- packet
+ }
+ // Look for all packets with the same source and destination network address
+ if net := packet.NetworkLayer(); net != nil {
+   src, dst := net.NetworkFlow().Endpoints()
+   if src == dst {
+     fmt.Println("Fishy packet has same network source and dst: %s", src)
+   }
+ }
+ // Find all packets coming from UDP port 1000 to UDP port 500
+ interestingFlow := gopacket.NewFlow(layers.NewUDPPortEndpoint(1000), layers.NewUDPPortEndpoint(500))
+ if t := packet.NetworkLayer(); t != nil && t.TransportFlow() == interestingFlow {
+   fmt.Println("Found that UDP flow I was looking for!")
+ }
+
+For load-balancing purposes, both Flow and Endpoint have FastHash() functions,
+which provide quick, non-cryptographic hashes of their contents.  Of particular
+importance is the fact that Flow FastHash() is symmetric: A->B will have the same
+hash as B->A.  An example usage could be:
+
+ channels := [8]chan gopacket.Packet
+ for i := 0; i < 8; i++ {
+   channels[i] = make(chan gopacket.Packet)
+   go packetHandler(channels[i])
+ }
+ for packet := range getPackets() {
+   if net := packet.NetworkLayer(); net != nil {
+     channels[int(net.NetworkFlow().FastHash()) & 0x7] <- packet
+   }
+ }
+
+This allows us to split up a packet stream while still making sure that each
+stream sees all packets for a flow (and its bidirectional opposite).
+
+
+Implementing Your Own Decoder
+
+If your network has some strange encapsulation, you can implement your own
+decoder.  In this example, we handle Ethernet packets which are encapsulated
+in a 4-byte header.
+
+ // Create a layer type, should be unique and high, so it doesn't conflict,
+ // giving it a name and a decoder to use.
+ var MyLayerType = gopacket.RegisterLayerType(12345, gopacket.LayerTypeMetadata{Name: "MyLayerType", Decoder: gopacket.DecodeFunc(decodeMyLayer)})
+
+ // Implement my layer
+ type MyLayer struct {
+   StrangeHeader []byte
+   payload []byte
+ }
+ func (m MyLayer) LayerType() gopacket.LayerType { return MyLayerType }
+ func (m MyLayer) LayerContents() []byte { return m.StrangeHeader }
+ func (m MyLayer) LayerPayload() []byte { return m.payload }
+
+ // Now implement a decoder... this one strips off the first 4 bytes of the
+ // packet.
+ func decodeMyLayer(data []byte, p gopacket.PacketBuilder) error {
+   // Create my layer
+   p.AddLayer(&MyLayer{data[:4], data[4:]})
+   // Determine how to handle the rest of the packet
+   return p.NextDecoder(layers.LayerTypeEthernet)
+ }
+
+ // Finally, decode your packets:
+ p := gopacket.NewPacket(data, MyLayerType, gopacket.Lazy)
+
+See the docs for Decoder and PacketBuilder for more details on how coding
+decoders works, or look at RegisterLayerType and RegisterEndpointType to see how
+to add layer/endpoint types to gopacket.
+
+
+Fast Decoding With DecodingLayerParser
+
+TLDR:  DecodingLayerParser takes about 10% of the time as NewPacket to decode
+packet data, but only for known packet stacks.
+
+Basic decoding using gopacket.NewPacket or PacketSource.Packets is somewhat slow
+due to its need to allocate a new packet and every respective layer.  It's very
+versatile and can handle all known layer types, but sometimes you really only
+care about a specific set of layers regardless, so that versatility is wasted.
+
+DecodingLayerParser avoids memory allocation altogether by decoding packet
+layers directly into preallocated objects, which you can then reference to get
+the packet's information.  A quick example:
+
+ func main() {
+   var eth layers.Ethernet
+   var ip4 layers.IPv4
+   var ip6 layers.IPv6
+   var tcp layers.TCP
+   parser := gopacket.NewDecodingLayerParser(layers.LayerTypeEthernet, &eth, &ip4, &ip6, &tcp)
+   decoded := []gopacket.LayerType{}
+   for packetData := range somehowGetPacketData() {
+     if err := parser.DecodeLayers(packetData, &decoded); err != nil {
+       fmt.Fprintf(os.Stderr, "Could not decode layers: %v\n", err)
+       continue
+     }
+     for _, layerType := range decoded {
+       switch layerType {
+         case layers.LayerTypeIPv6:
+           fmt.Println("    IP6 ", ip6.SrcIP, ip6.DstIP)
+         case layers.LayerTypeIPv4:
+           fmt.Println("    IP4 ", ip4.SrcIP, ip4.DstIP)
+       }
+     }
+   }
+ }
+
+The important thing to note here is that the parser is modifying the passed in
+layers (eth, ip4, ip6, tcp) instead of allocating new ones, thus greatly
+speeding up the decoding process.  It's even branching based on layer type...
+it'll handle an (eth, ip4, tcp) or (eth, ip6, tcp) stack.  However, it won't
+handle any other type... since no other decoders were passed in, an (eth, ip4,
+udp) stack will stop decoding after ip4, and only pass back [LayerTypeEthernet,
+LayerTypeIPv4] through the 'decoded' slice (along with an error saying it can't
+decode a UDP packet).
+
+Unfortunately, not all layers can be used by DecodingLayerParser... only those
+implementing the DecodingLayer interface are usable.  Also, it's possible to
+create DecodingLayers that are not themselves Layers... see
+layers.IPv6ExtensionSkipper for an example of this.
+
+
+Creating Packet Data
+
+As well as offering the ability to decode packet data, gopacket will allow you
+to create packets from scratch, as well.  A number of gopacket layers implement
+the SerializableLayer interface; these layers can be serialized to a []byte in
+the following manner:
+
+  ip := &layers.IPv4{
+    SrcIP: net.IP{1, 2, 3, 4},
+    DstIP: net.IP{5, 6, 7, 8},
+    // etc...
+  }
+  buf := gopacket.NewSerializeBuffer()
+  opts := gopacket.SerializeOptions{}  // See SerializeOptions for more details.
+  err := ip.SerializeTo(buf, opts)
+  if err != nil { panic(err) }
+  fmt.Println(buf.Bytes())  // prints out a byte slice containing the serialized IPv4 layer.
+
+SerializeTo PREPENDS the given layer onto the SerializeBuffer, and they treat
+the current buffer's Bytes() slice as the payload of the serializing layer.
+Therefore, you can serialize an entire packet by serializing a set of layers in
+reverse order (Payload, then TCP, then IP, then Ethernet, for example).  The
+SerializeBuffer's SerializeLayers function is a helper that does exactly that.
+
+To generate a (empty and useless, because no fields are set)
+Ethernet(IPv4(TCP(Payload))) packet, for example, you can run:
+
+  buf := gopacket.NewSerializeBuffer()
+  opts := gopacket.SerializeOptions{}
+  gopacket.SerializeLayers(buf, opts,
+    &layers.Ethernet{},
+    &layers.IPv4{},
+    &layers.TCP{},
+    gopacket.Payload([]byte{1, 2, 3, 4}))
+  packetData := buf.Bytes()
+
+A Final Note
+
+If you use gopacket, you'll almost definitely want to make sure gopacket/layers
+is imported, since when imported it sets all the LayerType variables and fills
+in a lot of interesting variables/maps (DecodersByLayerName, etc).  Therefore,
+it's recommended that even if you don't use any layers functions directly, you still import with:
+
+  import (
+    _ "github.com/google/gopacket/layers"
+  )

+Package layers provides decoding layers for many common protocols.
+
+The layers package contains decode implementations for a number of different
+types of packet layers.  Users of gopacket will almost always want to also use
+layers to actually decode packet data into useful pieces. To see the set of
+protocols that gopacket/layers is currently able to decode,
+look at the set of LayerTypes defined in the Variables sections. The
+layers package also defines endpoints for many of the common packet layers
+that have source/destination addresses associated with them, for example IPv4/6
+(IPs) and TCP/UDP (ports).
+Finally, layers contains a number of useful enumerations (IPProtocol,
+EthernetType, LinkType, PPPType, etc...).  Many of these implement the
+gopacket.Decoder interface, so they can be passed into gopacket as decoders.
+
+Most common protocol layers are named using acronyms or other industry-common
+names (IPv4, TCP, PPP).  Some of the less common ones have their names expanded
+(CiscoDiscoveryProtocol).
+For certain protocols, sub-parts of the protocol are split out into their own
+layers (SCTP, for example).  This is done mostly in cases where portions of the
+protocol may fulfill the capabilities of interesting layers (SCTPData implements
+ApplicationLayer, while base SCTP implements TransportLayer), or possibly
+because splitting a protocol into a few layers makes decoding easier.
+
+This package is meant to be used with its parent,
+http://github.com/google/gopacket.
+
+Port Types
+
+Instead of using raw uint16 or uint8 values for ports, we use a different port
+type for every protocol, for example TCPPort and UDPPort.  This allows us to
+override string behavior for each port, which we do by setting up port name
+maps (TCPPortNames, UDPPortNames, etc...).  Well-known ports are annotated with
+their protocol names, and their String function displays these names:
+
+  p := TCPPort(80)
+  fmt.Printf("Number: %d  String: %v", p, p)
+  // Prints: "Number: 80  String: 80(http)"
+
+Modifying Decode Behavior
+
+layers links together decoding through its enumerations.  For example, after
+decoding layer type Ethernet, it uses Ethernet.EthernetType as its next decoder.
+All enumerations that act as decoders, like EthernetType, can be modified by
+users depending on their preferences.  For example, if you have a spiffy new
+IPv4 decoder that works way better than the one built into layers, you can do
+this:
+
+ var mySpiffyIPv4Decoder gopacket.Decoder = ...
+ layers.EthernetTypeMetadata[EthernetTypeIPv4].DecodeWith = mySpiffyIPv4Decoder
+
+This will make all future ethernet packets use your new decoder to decode IPv4
+packets, instead of the built-in decoder used by gopacket.

+// About The Network Time Protocol (NTP)
+// -------------------------------------
+// NTP is a protocol that enables computers on the internet to set their
+// clocks to the correct time (or to a time that is acceptably close to the
+// correct time). NTP runs on top of UDP.
+//
+// There have been a series of versions of the NTP protocol. The latest
+// version is V4 and is specified in RFC 5905:
+//     http://www.ietf.org/rfc/rfc5905.txt
+//

+//
+//    BIT NUMBERING: Bits are numbered 0 upwards from the most significant
+//    bit to the least significant bit. This means that if there is a 32-bit
+//    value, the most significant bit is called bit 0 and the least
+//    significant bit is called bit 31.

+//******************************************************************************
+//
+// NTP V3 and V4 Packet Format
+// ---------------------------
+// NTP packets are UDP packets whose payload contains an NTP record.
+//
+// The NTP RFC defines the format of the NTP record.
+//
+// There have been four versions of the protocol:
+//
+//    V1 in 1985
+//    V2 in 1989
+//    V3 in 1992
+//    V4 in 2010
+//
+// It is clear that V1 and V2 are obsolete, and there is no need to
+// cater for these formats.
+//
+// V3 and V4 essentially use the same format, with V4 adding some optional
+// fields on the end. So this package supports the V3 and V4 formats.
+//
+// The current version of NTP (NTP V4)'s RFC (V4 - RFC 5905) contains
+// the following diagram for the NTP record format:
+
+//      0                   1                   2                   3

+This layer decodes SFlow version 5 datagrams.
+
+The specification can be found here: http://sflow.org/sflow_version_5.txt
+
+Additional developer information about sflow can be found at:
+http://sflow.org/developers/specifications.php
+
+And SFlow in general:
+http://sflow.org/index.php
+
+Two forms of sample data are defined: compact and expanded. The
+Specification has this to say:
+
+    Compact and expand forms of counter and flow samples are defined.
+    An agent must not mix compact/expanded encodings.  If an agent
+    will never use ifIndex numbers >= 2^24 then it must use compact
+    encodings for all interfaces.  Otherwise the expanded formats must
+    be used for all interfaces.
+
+This decoder only supports the compact form, because that is the only
+one for which data was avaialble.
+
+The datagram is composed of one or more samples of type flow or counter,
+and each sample is composed of one or more records describing the sample.
+A sample is a single instance of sampled inforamtion, and each record in
+the sample gives additional / supplimentary information about the sample.
+
+The following sample record types are supported:
+
+	Raw Packet Header
+	opaque = flow_data; enterprise = 0; format = 1
+
+	Extended Switch Data
+	opaque = flow_data; enterprise = 0; format = 1001
+
+	Extended Router Data
+	opaque = flow_data; enterprise = 0; format = 1002
+
+	Extended Gateway Data
+	opaque = flow_data; enterprise = 0; format = 1003
+
+	Extended User Data
+	opaque = flow_data; enterprise = 0; format = 1004
+
+	Extended URL Data
+	opaque = flow_data; enterprise = 0; format = 1005
+
+The following types of counter records are supported:
+
+	Generic Interface Counters - see RFC 2233
+	opaque = counter_data; enterprise = 0; format = 1
+
+	Ethernet Interface Counters - see RFC 2358
+	opaque = counter_data; enterprise = 0; format = 2
+
+SFlow is encoded using XDR (RFC4506). There are a few places
+where the standard 4-byte fields are partitioned into two
+bitfields of different lengths. I'm not sure why the designers
+chose to pack together two values like this in some places, and
+in others they use the entire 4-byte value to store a number that
+will never be more than a few bits. In any case, there are a couple
+of types defined to handle the decoding of these bitfields, and
+that's why they're there. */

+Package pcap allows users of gopacket to read packets off the wire or from
+pcap files.
+
+This package is meant to be used with its parent,
+http://github.com/google/gopacket, although it can also be used independently
+if you just want to get packet data from the wire.
+
+Depending on libpcap version, os support, or file timestamp resolution,
+nanosecond resolution is used for the internal timestamps. Returned timestamps
+are always scaled to nanosecond resolution due to the usage of time.Time.
+libpcap must be at least version 1.5 to support nanosecond timestamps. OpenLive
+supports only microsecond resolution.
+
+Reading PCAP Files
+
+The following code can be used to read in data from a pcap file.
+
+ if handle, err := pcap.OpenOffline("/path/to/my/file"); err != nil {
+   panic(err)
+ } else {
+   packetSource := gopacket.NewPacketSource(handle, handle.LinkType())
+   for packet := range packetSource.Packets() {
+     handlePacket(packet)  // Do something with a packet here.
+   }
+ }
+
+Reading Live Packets
+
+The following code can be used to read in data from a live device, in this case
+"eth0". Be aware, that OpenLive only supports microsecond resolution.
+
+ if handle, err := pcap.OpenLive("eth0", 1600, true, pcap.BlockForever); err != nil {
+   panic(err)
+ } else if err := handle.SetBPFFilter("tcp and port 80"); err != nil {  // optional
+   panic(err)
+ } else {
+   packetSource := gopacket.NewPacketSource(handle, handle.LinkType())
+   for packet := range packetSource.Packets() {
+     handlePacket(packet)  // Do something with a packet here.
+   }
+ }
+
+Inactive Handles
+
+Newer PCAP functionality requires the concept of an 'inactive' PCAP handle.
+Instead of constantly adding new arguments to pcap_open_live, users now call
+pcap_create to create a handle, set it up with a bunch of optional function
+calls, then call pcap_activate to activate it.  This library mirrors that
+mechanism, for those that want to expose/use these new features:
+
+  inactive, err := pcap.NewInactiveHandle(deviceName)
+  if err != nil {
+    log.Fatal(err)
+  }
+  defer inactive.CleanUp()
+
+  // Call various functions on inactive to set it up the way you'd like:
+  if err = inactive.SetTimeout(time.Minute); err != nil {
+    log.Fatal(err)
+  } else if err = inactive.SetTimestampSource("foo"); err != nil {
+    log.Fatal(err)
+  }
+
+  // Finally, create the actual handle by calling Activate:
+  handle, err := inactive.Activate()  // after this, inactive is no longer valid
+  if err != nil {
+    log.Fatal(err)
+  }
+  defer handle.Close()
+
+  // Now use your handle as you see fit.
+
+PCAP Timeouts
+
+pcap.OpenLive and pcap.SetTimeout both take timeouts.
+If you don't care about timeouts, just pass in BlockForever,
+which should do what you expect with minimal fuss.
+
+A timeout of 0 is not recommended.  Some platforms, like Macs
+(http://www.manpages.info/macosx/pcap.3.html) say:
+  The read timeout is used to arrange that the read not necessarily return
+  immediately when a packet is seen, but that it wait for some amount of time
+  to allow more packets to arrive and to read multiple packets from the OS
+  kernel in one operation.
+This means that if you only capture one packet, the kernel might decide to wait
+'timeout' for more packets to batch with it before returning.  A timeout of
+0, then, means 'wait forever for more packets', which is... not good.
+
+To get around this, we've introduced the following behavior:  if a negative
+timeout is passed in, we set the positive timeout in the handle, then loop
+internally in ReadPacketData/ZeroCopyReadPacketData when we see timeout
+errors.
+
+PCAP File Writing
+
+This package does not implement PCAP file writing.  However, gopacket/pcapgo
+does!  Look there if you'd like to write PCAP files.
+
+Note For Windows Users
+
+gopacket can use winpcap or npcap. If both are installed at the same time,
+npcap is preferred. Make sure the right windows service is loaded (npcap for npcap
+and npf for winpcap).

+// Byte slices returned by PrependBytes/AppendBytes are NOT zero'd out, so if
+// you want to make sure they're all zeros, set them as such.
+//
+// SerializeBuffer is specifically designed to handle packet writing, where unlike

+// work out, meaning that we often need to prepend bytes.  This runs counter to
+// typical writes to byte slices using append(), where we only write at the end

+//  2) If a byte slice from a previous Bytes() call will continue to be used,
+//     it's better to create a new SerializeBuffer.
