Commit Message

Rongwei Liu July 5, 2021, 9:50 a.m. UTC 
  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.
