/* OpenFlow: protocol between controller and datapath. */
/*
* This is a relatively straightforward rendering of OpenFlow message
* definitions into protocol buffer messages. We preserved the snake
* case syntax, and made the following changes:
* - all pad fields dropped
* - for each enum value above 0x7fffffff the MSB is dropped. For example,
* 0xffffffff is now 0x7fffffff.
* - '<type> thing[...]' is replaced with 'repeated <type> thing'
* - 'char thing[...]' is replaced with 'string thing'
* - 'uint8_t data[...]' is replaced with 'bytes data'
* - the following systematic changes are done to various integer types:
* uint8_t -> uint32
* uint16_t -> uint32
* uint32_t -> uint32
* uint64_t -> uint64
* - removed most length, len, size fields where these values can be determined
* from the explicitly encoded length of "repeated" protobuf fields.
* - explicit use of enum types whereever it is unambigous (and not used as
* bitmask/flags value.
*
