bna: Tx and Rx Optimizations
Change details:
- Have contiguous queue pages for TxQ, RxQ and CQ. Data structure and
QPT changes related to contiguous queue pages
- Optimized Tx and Rx unmap structures. Tx and Rx fast path changes due to
unmap data structure changes
- Re-factored Tx and Rx fastpath routines as per the new queue data structures
- Implemented bnad_txq_wi_prepare() to program the opcode, flags, frame_len
and num_vectors in the work item
- Reduced Max TxQ and RxQ depth to 2048 while default value for Tx/Rx queue
depth is unaltered (512)
