Merge branch 'mlx4-XDP-performance-improvements'
Tariq Toukan says:
====================
mlx4 XDP performance improvements
This patchset contains data-path improvements, mainly for XDP_DROP
and XDP_TX cases.
Main patches:
* Patch 2 by Saeed allows enabling optimized A0 RX steering (in HW) when
setting a single RX ring.
With this configuration, HW packet-rate dramatically improves,
reaching 28.1 Mpps in XDP_DROP case for both IPv4 (37% gain)
and IPv6 (53% gain).
* Patch 6 enhances the XDP xmit function. Among other changes, now we
ring one doorbell per NAPI. Patch gives 17% gain in XDP_TX case.
* Patch 7 obsoletes the NAPI of XDP_TX completion queue and integrates its
poll into the respective RX NAPI. Patch gives 15% gain in XDP_TX case.
