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.
