Hi,

FYI, your patch has been queued to stable release 20.11.10

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/21/23. 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://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/cc0f2200f0d8ae5175dc8185245493d24bb1c667

Thanks.

Luca Boccassi

Subject: [PATCH] net/txgbe: reconfigure MAC Rx when link update

[ 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")
