+      <text>`Any` contains an arbitrary serialized protocol buffer message along with a
+URL that describes the type of the serialized message.
+
+Protobuf library provides support to pack unpack Any values in the form
+of utility functions or additional generated methods of the Any type.
+
+Example 1: Pack and unpack a message in C++.
+
+Foo foo = ...;
+Any any;
+any.PackFrom(foo);
+...
+if (any.UnpackTo(&amp;amp;foo))
+...
+
+
+Example 2: Pack and unpack a message in Java.
+
+Foo foo = ...;
+Any any = Any.pack(foo);
+...
+if (any.is(Foo.class))
+foo = any.unpack(Foo.class);
+
+
+Example 3: Pack and unpack a message in Python.
+
+foo = Foo(...)
+any = Any()
+any.Pack(foo)
+...
+if any.Is(Foo.DESCRIPTOR):
+any.Unpack(foo)
+...
+
+The pack methods provided by protobuf library will by default use
+'type.googleapis.com full.type.name' as the type URL and the unpack
+methods only use the fully qualified type name after the last ' '
+in the type URL, for example  foo.bar.com x y.z  will yield type
+name  y.z .
+
+
+JSON
+====
+The JSON representation of an `Any` value uses the regular
+representation of the deserialized, embedded message, with an
+additional field `@type` which contains the type URL. Example:
+
+package google.profile;
+message Person
+string first_name = 1;
+string last_name = 2;
+
+
+
+@type :  type.googleapis.com google.profile.Person ,
+firstName :  string ,
+lastName :  string
+
+
+If the embedded message type is well-known and has a custom JSON
+representation, that representation will be embedded adding a field
+`value` which holds the custom JSON in addition to the `@type`
+field. Example (for message  google.protobuf.Duration   ):
+
+
+@type :  type.googleapis.com google.protobuf.Duration ,
+value :  1.212s

+    <leaf name="type_url">
+      <type name="string"/>
+      <description>
+        <text>A URL resource name whose content describes the type of the
+serialized protocol buffer message.
+
+For URLs which use the scheme `http`, `https`, or no scheme, the
+following restrictions and interpretations apply:
+
+If no scheme is provided, `https` is assumed.
+The last segment of the URL's path must represent the fully
+qualified name of the type (as in `path google.protobuf.Duration`).
+The name should be in a canonical form (e.g., leading  .  is
+not accepted).
+An HTTP GET on the URL must yield a  google.protobuf.Type
+value in binary format, or produce an error.
+Applications are allowed to cache lookup results based on the
+URL, or have them precompiled into a binary to avoid any
+lookup. Therefore, binary compatibility needs to be preserved
+on changes to types. (Use versioned type names to manage
+breaking changes.)
+
+Schemes other than `http`, `https` (or the empty scheme) might be
+used with implementation specific semantics.</text>

+- Equal (OFPCR_ROLE_EQUAL), which allows the controller access to all
+OpenFlow features. All controllers have equal responsibility.
+
+The other possible roles are a related pair:
+
+- Master (OFPCR_ROLE_MASTER) is equivalent to Equal, except that there
+may be at most one Master controller at a time: when a controller
+configures itself as Master, any existing Master is demoted to the
+Slave role.
+
+- Slave (OFPCR_ROLE_SLAVE) allows the controller read-only access to
+OpenFlow features.  In particular attempts to modify the flow table
+will be rejected with an OFPBRC_EPERM error.
+
+Slave controllers do not receive OFPT_PACKET_IN or OFPT_FLOW_REMOVED
+messages, but they do receive OFPT_PORT_STATUS messages.</text>

+Consider a packet received on a tunnel interface defined over a link

+OFPXMT_OF_IN_PORT is the tunnel's port number and OFPXMT_OF_IN_PHY_PORT is

+
+When a packet is received directly on a physical port and not processed by a
