Hi,
FYI, your patch has been queued to stable release 22.11.4
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/15/23. 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=f76fc5ef15ee257bf406cb29ecbb218061cc0f2f
Thanks.

Subject: [PATCH] eal/unix: fix firmware reading with external xz helper
Cc: Xueming Li <xuemingl at nvidia.com>
[ upstream commit 39970abcf4850e070aa4709c87bcac15cb27caf8 ]
libarchive may support xz decompression only through an
external (slower) helper.
In such a case, archive_read_support_filter_xz() returns
ARCHIVE_WARN.
Fixes: 40edb9c0d36b ("eal: handle compressed firmware")
