patch 'net/mlx5: fix shared counter flag in flow validation' has been queued to stable release 21.11.1

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/14/22. 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/4de91bc1a8a19ccdea3cce67dff939ab34cf0275

Thanks.

Kevin

Subject: [PATCH] net/mlx5: fix shared counter flag in flow validation

[ upstream commit 8f53c7cf2660a2a5d2a61fefe987491bce50edde ]

The AGE action can be implemented by either counters or ASO mechanism.
When user ask count action in the flow rule, AGE action is implemented
by the same counter. However, if user ask indirect count action, it
cannot be used for AGE.

The flow_dv_validate() function has a flag named "shared_count" which
indicates whether AGE action validate depends on ASO support or not.
This flag is initialized to false and is updated if there is indirect
count action in the action list.
This flag is mistakenly set within the loop that reads the action list
and in each iteration it is reinitialized to false, regardless of the
existence of an indirect count action in the list.

This patch moves the flag initialization out of the loop.

Fixes: f3191849f2c2 ("net/mlx5: support flow count action handle")
