Daniel Borkmann 4d463c4dbc xdp: use common helper for netlink extended ack reporting ... Small follow-up to d74a32acd5 ("xdp: use netlink extended ACK reporting") in order to let drivers all use the same NL_SET_ERR_MSG_MOD() helper macro for reporting. This also ensures that we consistently add the driver's prefix for dumping the report in user space to indicate that the error message is driver specific and not coming from core code. Furthermore, NL_SET_ERR_MSG_MOD() now reuses NL_SET_ERR_MSG() and thus makes all macros check the pointer as suggested.
