This series of patches rework TX and RX path to reduce latency and improve performance.
Patch 1 reduces latency for slow traffic by using status page update on RX path to process batch of packets and improves coalesce TX path to handle slow moving traffic. Patch 2 fixes an issue with RXQ default parameters not being applied to all ports under same PF. Patch 3 fixes rmb bottleneck in RX path. Patch 4 adds ability to configure PCIe extended tags.
