patch 'net/bnxt: fix mutexes for multi-process' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/27/26. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/bc57b898c3fd7e5048719bdc392129382555698a

Thanks.

Kevin

Subject: [PATCH] net/bnxt: fix mutexes for multi-process

[ upstream commit 5b209eb21a98ce8d396d9fc58ee4710ce94778be ]

The BNXT driver supports secondary processes. Several mutexes live in
structures allocated in shared memory (dev_private and rte_zmalloc'd
structures) and must be initialized with PTHREAD_PROCESS_SHARED:

  - flow_lock, def_cp_lock, health_check_lock, err_recovery_lock
    in struct bnxt
  - vfr_start_lock in rep_info
  - txq_lock in struct bnxt_tx_queue
  - bnxt_ulp_mutex in session state
  - flow_db_lock in cfg_data

Bugzilla ID: 662
Fixes: 1cb3d39a48f7 ("net/bnxt: synchronize between flow related functions")
Fixes: 5526c8025d4d ("net/bnxt: fix race between interrupt handler and dev config")
Fixes: b59e4be2b6a7 ("net/bnxt: fix VF representor port add")
