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.
