[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 23.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
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=ef2e66caed01481bea22fcb5f75a2dc2fa4ef12c

Subject: [PATCH] net/igc/base: fix unused value
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit c506cc8305b4ca17bae903a54daaeaf5b7005038 ]

Static analysis has reported that when there is no get link status
callback function, the value set in the if condition is not used and
gets overwritten in the "out" section of the code. Fix by not setting
the variable.

Fixes: 8cb7c57d9b3c ("net/igc: support device initialization")
