[v5,2/2] app/testpmd: support VXLAN the last 8-bits field matching
Checks
Commit Message
Add a new testpmd pattern field 'last_rsvd' that supports the
last 8-bits matching of VXLAN header.
The examples for the "last_rsvd" pattern field are as below:
1. ...pattern eth / ipv4 / udp / vxlan last_rsvd is 0x80 / end ...
This flow will exactly match the last 8-bits to be 0x80.
2. ...pattern eth / ipv4 / udp / vxlan last_rsvd spec 0x80
vxlan mask 0x80 / end ...
This flow will only match the MSB of the last 8-bits to be 1.

This change should be part of the first patch not related to testpmd part.
Also, how about something like this:
Added support for matching on the reserved filed of VXLAN header (last 8-bits).

Kindest regards

Also it should be merged with already existing "Updated
Mellanox mlx5 driver." in 21.08 release notes.
