[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=d50c5a9ace9d836d20e57b1ed41c87a54bbdeb01

Subject: [PATCH] net/igc/base: reset loop variable
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit 60dca8e0f6b2d8526dc9dc8b54e59b5d68964e8e ]

When writing to Shadow RAM, we set rev_val on success, but since the
value is already set to success initially, it is possible for none of
the writes to be successful, yet ret_val will still be set to success.
Fix it by resetting the ret_val to failure before every loop iteration.

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