patch 'net/mlx5: fix validation of sample encap flow action' has been queued to stable release 21.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/21/23. 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/02b97af64b1b58ed1e13722367fe9b8a1595c6db

Thanks.

Subject: [PATCH] net/mlx5: fix validation of sample encap flow action

[ upstream commit a2a709f0e7b88b785acaae87dd9724821438c969 ]

The flow sample/mirror action includes sub-actions for the
duplicated packet.
In SW steering case, dv_flow_en=1, there is a FW limitation
that forces configuring also encap action when port action
for the wire port is configured in the duplicated packet's
sub-actions.

The driver did a wrong validation for the above limitation
and forced other actions instead of encap for the wire port.
Force only encap action in case of wire port.

This patch fixes the wrongly checking for the sample encap action.

Fixes: a8697f50f50f ("net/mlx5: fix E-Switch mirror flow rule validation")
