patch 'net/axgbe: fix fluctuations for 1G Bel Fuse SFP' has been queued to stable release 23.11.2

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/14/24. 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://git.dpdk.org/dpdk-stable/log/?h=23.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=23.11-staging&id=5f0956a06c3afc43c3dc8477ba81d10a25be37f6

Thanks.

Subject: [PATCH] net/axgbe: fix fluctuations for 1G Bel Fuse SFP
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 3abfda0f7d58b2eef20cdf8e102825678b150421 ]

Frequent link up/down events can happen when a Bel Fuse SFP part is
connected to the amd-xgbe device. Try to avoid the frequent link
issues by resetting the PHY as documented in Bel Fuse SFP datasheet.

Without the fix user will see continuous port link up and down.

Fixes: a5c7273771e8 ("net/axgbe: add phy programming APIs")
