[dpdk-stable] patch 'net/i40e: fix using recovery mode firmware' has been queued to stable release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/18/18. 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.

Kevin Traynor

Subject: [PATCH] net/i40e: fix using recovery mode firmware

[ upstream commit 81b531cfc235149f68a40842abf0767a4fbfe994 ]

Device can't function properly with a firmware that is in recovery
mode.

Check the firmware status at initialization time. If the firmware is
in recovery mode, alert the user to check it.
