I'd say tx_ring is false, rather than NULL.

v1 = replace if()/BUG with BUG_ON() for tx_ring. v2 = remove handling of tx_ring in prb_setup_retire_blk_timer for TPACKET_V3 because init_prb_bdqc is called only for NULL tx_ring and thus prb_setup_retire_blk_timer for NULL tx_ring only. And also in funciton init_prb_bdqc there is no usage of tx_ring. Thus removing tx_ring from init_prb_bdqc.
