[PATCH] net/mlx5: support matching optional fields of GRE

[Thomas Monjalon]

17/02/2022 07:27, Sean Zhang:
> This patch adds matching on the optional fields (checksum/key/sequence)
> of GRE header. The matching on checksum and sequence fields requests
> support from rdma-core with the capability of misc5 and tunnel_header 0-3.
> 
> For patterns without checksum and sequence specified, keep using misc for
> matching as before, but for patterns with checksum or sequence, validate
> capability first and then use misc5 for the matching.

Should we add a line in the release notes?
