This patchset improves the mlx5 PMD performance by doing better prefetching,
by reordering internal structure fields and by removing a few unnecessary
operations.
Note: should be applied after "Add flow director and RX VLAN stripping
support" to avoid conflicts.
Changes in v3:
- None, submitted again due to dependency with previous patchset.
Changes in v2:
- Rebased patchset on top of dpdk-next-net/rel_16_04.
- Fixed missing update for receive function in rxq_rehash().
- Added a commit to register memory on page boundaries instead of mempool
object boundaries for better performance (mlx4 and mlx5).
Adrien Mazarguil (1):
mlx: use aligned memory to register regions
Nelio Laranjeiro (6):
mlx5: prefetch next TX mbuf header and data
mlx5: reorder TX/RX queue structure
mlx5: remove one indirection level from RX/TX functions
mlx5: process offload flags only when requested
mlx5: avoid lkey retrieval for inlined packets
mlx5: free buffers immediately after completion
