Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/26. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/ef5d513e4f88d0351b15ee333beabd5e2831d844

Thanks.

Luca Boccassi

Subject: [PATCH] net/atlantic: fix mbox mutex for multi-process

[ upstream commit 3ee53df7864c7f1ddcf3d848daeec43afa2cd6bc ]

The Atlantic driver supports secondary processes. The mbox_mutex in
aq_hw_s lives in dev_private (shared memory) and must be initialized
with PTHREAD_PROCESS_SHARED.

Bugzilla ID: 662
Fixes: e9924638f5c9 ("net/atlantic: add FW mailbox guard mutex")
