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.
