Re: [PATCH v4 0/5] net/mlx5: add vectorized Rx/Tx burst for x86

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.

v4:
* Restore 'pragma' for PEDANTIC.
* Resolve compile error with clang.

v3:
* Remove requirement of SSE4.1 as DPDK now mandates SSE4.2 support at least.
* Bug fix in "net/mlx5: select Rx/Tx callbacks when starting device"
  - Need to re-select Rx burst func when chaning MTU size.
* Resolved an optimization issue of gcc-6 in rxq_burst_v()
  - Bit shift (<<) for 128b vector type is compiled differently. 'psllq' is
    needed instead of 'sal'.
* Minor changes to address what is mentioned by review.
  - Remove 'pragma' for PEDANTIC
  - Make mlx5_ptype_table global.
  - Change name of some inline funcs which also exist in mlx4 by the same name.
  - Fix comments and indentation/spacing.

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 x86

Series applied to dpdk-next-net/master, thanks.
