Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/17/24. 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/a51a250cc5bdfae4479d6fc1a38a041877045811

Thanks.

Luca Boccassi

Subject: [PATCH] net/ngbe: fix MTU range

[ upstream commit df2075eb681111637d5340c9abaf60e0aefab615 ]

The valid range of MTU is 68 to 9414. Set min_mtu and max_mtu in
dev_info.

Fixes: 07baabb6a51a ("net/ngbe: support MTU set")
