patch 'net/sfc: fix MAC address entry leak in transfer flow parsing' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/01/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=be7d6baf283b04ed23727b931494931c019bf6c6

Thanks.

Subject: [PATCH] net/sfc: fix MAC address entry leak in transfer flow parsing
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 97f7e36ad946986a14903db68b6770aacaf53ae1 ]

When the action parsing helper discovers it can "attach" to
an existing action set, it must invoke "delete" on the MAC
address(es) that it has "attached" to during parsing. That
is because the action set itself (i.e. not the flow rule
entry) holds a reference of the address(es).

Fixes: 4c6005999e41 ("net/sfc: support MAC address edits in transfer flows")
