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 10/29/26. 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/b74997b5202d871f13289df4b6037de2cddcea1d

Thanks.

Luca Boccassi

Subject: [PATCH] net/enic: check notify set return value during init

[ upstream commit 7b3647137055811a0f6d3fe43da517cf9ba11c9b ]

The return value of vnic_dev_notify_set() is silently ignored in
enic_dev_init(), so a memory allocation failure or hardware command
error goes unnoticed and the driver continues with uninitialized
notification state.

Check the return value and propagate the error to abort probe when
notification setup fails.

Fixes: fefed3d1e62c ("enic: new driver")
