Merge branch 'qed-tunneling-offload'

Manish Chopra says:

====================
qed/qede: Add tunneling support

This patch series adds support for VXLAN, GRE and GENEVE tunnels
to be used over this driver. With this support, adapter can perform
TSO offload, inner/outer checksums offloads on TX and RX for
encapsulated packets.

V1->V2 [ Comments from Jesse Gross incorporated ]
* Drop general infrastructure change patch.
  "net: Make vxlan/geneve default udp ports public"
* Remove by default Linux default UDP ports configurations in driver.
  Instead, use general registration APIs for UDP port configurations
* Removing .ndo_features_check - we will add it later with proper change.

Please consider applying this series to net-next.
