patch 'common/idpf: fix memory leak on AVX512 Tx queue close' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/11/23. 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=520330cbb1764754866e416e04bb5abae3400923

Thanks.

Subject: [PATCH] common/idpf: fix memory leak on AVX512 Tx queue close
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit b28f22e8709661fb9927c8121bbd4257ddd9202a ]

When releasing mbufs for TX queue software ring of AVX512,
the mbuf in the range [i, tx_tail] should also be freed.
The variable i refers to the index of the last mbuf released
in the software ring.

Fixes: 5bf87b45b2c8 ("net/idpf: add AVX512 data path for single queue model")
