patch 'common/idpf/base: fix memory leaks on control queue' 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 06/27/23. 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=b9f3b81e9eae675b51be236741cfa6ae3d511ade

Thanks.

[ upstream commit e83aa09770603943f7abd1b736f8c01ea4273e16 ]

idpf_init_hw needs to free it's q_info.
idpf_clean_arq_element needs to return buffers via post_rx_buffs

Fixes: fb4ac04e9bfa ("common/idpf: introduce common library")
