[Intel-wired-lan] [next PATCH S22 12/14] i40e/i40evf: Add a new offload for RSS PCTYPE V2 for X722

From: Anjali Singhai Jain <anjali.singhai at intel.com>

X722 supports Expanded version of TCP, UDP PCTYPES for RSS.
Add a Virtchnl offload to support this.

Without this patch with X722 devices, driver will set wrong PCTYPES
for VF and UDP flows will not fan out.

Testing-Hints:
Try multiple UDP flows on VF driver to see they get spread out by RSS.
