37/*
38 * This is a relatively straightforward rendering of OpenFlow message
39 * definitions into protocol buffer messages. We preserved the snake
40 * case syntax, and made the following changes:
41 * - all pad fields dropped
42 * - for each enum value above 0x7fffffff the MSB is dropped. For example,
43 * 0xffffffff is now 0x7fffffff.
44 * - '<type> thing[...]' is replaced with 'repeated <type> thing'
45 * - 'char thing[...]' is replaced with 'string thing'
46 * - 'uint8_t data[...]' is replaced with 'bytes data'
47 * - the following systematic changes are done to various integer types:
48 * uint8_t -> uint32
49 * uint16_t -> uint32
50 * uint32_t -> uint32
51 * uint64_t -> uint64
52 * - removed most length, len, size fields where these values can be determined
53 * from the explicitly encoded length of "repeated" protobuf fields.
54 * - explicit use of enum types whereever it is unambigous (and not used as
55 * bitmask/flags value.
