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/13909e4ba2cd08b6477e8b8d2f5f42c459e7215b

Thanks.

Luca Boccassi

Subject: [PATCH] net/txgbe: reconfigure more MAC Rx registers

[ upstream commit 3056288933f06afa72f8611ab7c4accdd01899fa ]

When link status changes, there is a probability that no more packets
can be received on the port, due to hardware defects. These MAC Rx
registers should be reconfigured to fix this problem.

Fixes: 950a6954df13 ("net/txgbe: reconfigure MAC Rx when link update")
