- move cxgb_tx_common in to cxgb_multiq.c and rename to cxgb_tx - move cxgb_tx_common dependencies - further simplify cxgb_dequeue_packet for the non-multiqueue case - only launch one service thread per port in the non-multiq case - remove dead cleaning code from cxgb_sge.c - simplify PIO case substantially in by returning directly from mbuf collapse and just using m_copydata - remove gratuitous m_gethdr in the rx path - clarify freeing of mbufs in collapse
