[dpdk-stable] patch 'net/ixgbe: fix link status' has been queued to stable release 19.11.1

Hi,

FYI, your patch has been queued to stable release 19.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/13/20. 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.

Thanks.

Luca Boccassi

Subject: [PATCH] net/ixgbe: fix link status

[ upstream commit ff8162cb9571528c006f265a32730a463fd0b886 ]

The link status for ixgbevf is not correct when PF link up.
IXGBE_ESDP register is only used when media type is fiber.
