[dpdk-stable] patch 'net/i40e: fix link speed for X722' has been queued to LTS release 18.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/14/19. 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/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/2236b9e8fd48daf67bac584d0ce3d754a014994e

Thanks.

Kevin Traynor

Subject: [PATCH] net/i40e: fix link speed for X722

[ upstream commit f2310dddf41c19c9c1d77dbd857d4fab1fb368b7 ]

If disable LSC when launching testpmd with X722, shown
link speed is 20G but not 10G. It's caused by wrongly
parsed link speed.
Correct it according to X722 datasheet.

Fixes: eef2daf2e199 ("net/i40e: fix link update no wait")
