[PATCH v2 0/5] net/mlx5: add vectorized Rx/Tx burst for x86

[Yongseok Koh <yskoh@mellanox.com>]

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.

Yongseok Koh (5):
  net/mlx5: change indexing for Tx SW ring
  net/mlx5: free buffers in bulk on Tx completion
  net/mlx5: use buffer address for LKEY search
  net/mlx5: select Rx/Tx callbacks when starting device
  net/mlx5: add vectorized Rx/Tx burst for SSE4.1
