Hi,
FYI, your patch has been queued to stable release 24.11.9
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/07/26. 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/2a8b77e646e17245912f9c8ac34faebd2eea5fe4
Thanks.

Subject: [PATCH] drivers/net: fix reported VMDq capability
[ upstream commit 7cf1306f707cf9aec379ec17cd30491ee41e9806 ]
Some PF drivers (dpaa, dpaa2) and VF drivers (ixgbe, ngbe, txgbe)
are announcing some VMDq capability though this support is not documented,
and no action is taken if the feature is requested.
fm10k announces capability for VF device, but rejects it at configure
time.
failsafe may support VMDq, as it only passes the requests to the ports
attached to it, hence mark it as partial support.
Fixes: fe3a45fd4104 ("ixgbe: add VMDq support")
Fixes: 7e72cbfa320b ("fm10k: add reta query/update")
Fixes: 799db4568c76 ("net/dpaa: support device info and speed capability")
Fixes: 762b275f20f8 ("net/dpaa2: add missing device info fields")
Fixes: c01c748e4ae6 ("net/ipn3ke: add new driver")
Fixes: 5dec0169554b ("net/txgbe: support VF get information")
Fixes: 66070ca419c1 ("net/ngbe: add hardware configuration for VF device")
