[dpdk-stable] patch 'net/mlx5: fix artificial L4 limitation on switch flow rules' has been queued to stable release 18.08.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.08.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/23/18. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Kevin Traynor

Subject: [PATCH] net/mlx5: fix artificial L4 limitation on switch flow rules

[ upstream commit dce1e4c2044d0e197eee29182cdb93454a0dc3d5 ]

Partial bit-masks are in fact supported on TCP/UDP source/destination
ports. Remove unnecessary check.

Fixes: 2bfc777e07 ("net/mlx5: add L2-L4 pattern items to switch flow rules")
