Hi,

FYI, your patch has been queued to stable release 22.11.8

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/19/25. 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/04fd449b89969b4d9413e84630411cd0baf5f11b

Thanks.

Luca Boccassi

Subject: [PATCH] net/igc/base: increase PHY power up delay

[ upstream commit a8a4acb46fa6bbe0a669b4eca0f73f112a7646ac ]

PHY specification for i225 requires 300 microsecond delay after power up
sequence, so increase the delay after power up to 300 microseconds.

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