37  * This macro cleans up the definitions of constants for BTH opcodes.
38  * It is used to define constants such as IBV_OPCODE_UD_SEND_ONLY,
39  * which becomes IBV_OPCODE_UD + IBV_OPCODE_SEND_ONLY, and this gives
40  * the correct value.
41  *
42  * In short, user code should use the constants defined using the
43  * macro rather than worrying about adding together other constants.
