This is to introduce more efficient Rx/Tx burst functions using SIMD instructions. Currently it is only supported by 64bit x86 having SSE4.1.
>From functional perspective, Rx burst function is equivalent to the existing mlx5_rx_burst() except for scatter support, which will be added soon. Tx burst function supports multi-segment packets and offload flags unless it is disabled by txq_flags. However, disabling those features will bring a little higher performance. v2: * Streamline redundant conditional clauses in txq_complete(). * Remove the mempool pointer in txq->mp2mr structure. * Fix indentation and spacing.
