Tx command is prepared based on offloads enabled and stored in Tx queue structure at tx_queue_setup phase. In fastpath the command is copied from Tx queue to LMT line for all the packets. Since, the command contents are mostly constants we can move the command preparation to fastpath and avoid accessing Tx queue memory.
