[dpdk-dev] [PATCH v5 0/8] net/mlx4: Tx path improvements

[Matan Azrad]

v1:
This series is a follow-up of the new datapath implementation introduced in RC1.
It is dedicated to Tx and improves the performance.

v2:
Change uint32_t be_lkey to rte_be32_t lkey

v3:
Rebase to 17.11-rc2.
Remove "net/mlx4: save lkey in big-endian format" patch which degrade performance.
Merge separate segment cases patches "net/mlx4: improve performance of one Tx segment" and "net/mlx4: separate Tx for multi-segments".
"net/mlx4: inline more Tx functions" renamed to "net/mlx4: associate MR to MP in a short function".
Leave bytes counter as old version.
Add memory barrier improvement patch.
Remove empty segment support.

v4:
Remove "net/mlx4: remove empty Tx segment support" patch.
Add "fix ring wraparound compiler hint" patch.
Add "fix HW memory optimizations careless" patch.
Remove unnecessary IO memory barrier in completion function.
Remove inline declaration of completion function.
Fix unnecessary empty lines.
Fix indetations.
Move max=0 check removal to patch "remove duplicate handling in Tx burst" and rename the patch.
Add performace improvement in patch "mitigate Tx path memory barriers"

v5:
Fix compilation issue in debug mode for patch "net/mlx4: associate MR to MP in a short function".
Add missing includes in "net/mlx4: associate MR to MP in a short function".
Add cq_uar as volatile too in "net/mlx4: fix HW memory optimizations careless".
Fix indentation issues in "net/mlx4: separate Tx segment cases".

  net/mlx4: remove error flows from Tx fast path
  net/mlx4: fix ring wraparound compiler hint
  net/mlx4: merge Tx path functions
  net/mlx4: remove duplicate handling in Tx burst
  net/mlx4: separate Tx segment cases
  net/mlx4: fix HW memory optimizations careless
  net/mlx4: mitigate Tx path memory barriers
