patch 'net/txgbe: reconfigure MAC Rx when link update' has been queued to stable release 22.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/15/23. 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/commit/?h=22.11-staging&id=768e6a3d839b622e4f3981a8b053e5b6e522a735

Thanks.

Subject: [PATCH] net/txgbe: reconfigure MAC Rx when link update
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 950a6954df134f8bff41fc7ad541a9c9730a4201 ]

Fix the bug that after setting flow control parameters, link status
change (for example, hot-plug SFP module) causes the port to no longer
receive packets.

Fixes: 0c061eadec59 ("net/txgbe: add link status change")
