If ib_post_send_mad() returns 0, the API guarantees that there will be a callback to send_buf->mad_agent->send_handler() so that the sender can call ib_free_send_mad(). Otherwise, the ib_mad_send_buf will be leaked and the mad_agent reference count will never go to zero and the IB device module cannot be unloaded. The above can happen without this patch if process_mad() returns (IB_MAD_RESULT_SUCCESS | IB_MAD_RESULT_CONSUMED). If process_mad() returns IB_MAD_RESULT_SUCCESS and there is no agent registered to receive the mad being sent, handle_outgoing_dr_smp() returns zero which causes a MAD packet which is at the end of the directed route to be incorrectly sent on the wire but doesn't cause a hang since the HCA generates a send completion.
