patch 'net/i40e: fix maximum frame size configuration' has been queued to stable release 22.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 04/11/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/log/?h=22.11-staging/commit/8ec56c115aa1debcc3f672eb95ba646e9b2d6da5

Thanks.

Subject: [PATCH] net/i40e: fix maximum frame size configuration
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 82fcf20d039c5990ea7829cea2996c530d260fab ]

This patch sets max frame size at port level rather than queue level
to avoid unexpected packets received by port.

Fixes: a8ca8edf8c07 ("net/i40e: revert link status check on device start")
