PS2, Line 19: 	 memcmp(msgb_data(msg), rtp_dummy_payload, sizeof(rtp_dummy_payload)) == 0))
> this here is sufficient, no need to add a char array and redundant checks: […]
when rtp_dummy_load is only one byte the compiler should optimize out the memcmp(). If it is more then one byte the left expression of the || should be optimized out.

(I would have used a sizeof() comparison with an #if and made it two differen macros, but sizeof is not possible on preprocessor level)
