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.
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.
