patch 'net/e1000/base: fix link power down' has been queued to stable release 21.11.8

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/28/24. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/f7f0ac1a361cdd631aabfc999e5aa6fe5329f017

Thanks.

Kevin

Subject: [PATCH] net/e1000/base: fix link power down

[ upstream commit a8218d09e3aaae5307325ff4b2f92ed4a3c37a8c ]

Current code is a result of work to reduce duplication between various
device models. However, the logic that was replaced did not exactly
match the new logic, and as a result the link power down was not
working correctly for some NICs, and the link remained up even when
the interface is down.

Fix it to correctly power down the link under all circumstances that
were supported by old logic.

Fixes: 44dddd14059f ("net/e1000/base: remove duplicated codes")
