patch 'net/iavf: fix pattern check for flow director parser' has been queued to stable release 21.11.3

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/01/22. 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. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/246026e0b89911ad715a723faef429e4c3e3f9f1

Thanks.

Kevin

Subject: [PATCH] net/iavf: fix pattern check for flow director parser

[ upstream commit e5c7498fae094e97a8e8831979a7112fa260bf92 ]

FDIR rules with masks are not supported in current code. Thus add
pattern check for IPv4/UDP/TCP/SCTP addr/port to terminate the FDIR
programming stage.

Fixes: d5eb3e600d9e ("net/iavf: support flow director basic rule")
