cxgb4: add Tx and Rx path for ETHOFLD traffic
Implement Tx path for traffic flowing through software EOSW_TXQ
and EOHW_TXQ. Since multiple EOSW_TXQ can post packets to a single
EOHW_TXQ, protect the hardware queue with necessary spinlock. Also,
move common code used to generate TSO work request to a common
function.
Implement Rx path to handle Tx completions for successfully
transmitted packets.
