Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/29/19. 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/87a7d973dc3bab38be39a6abd0c611ff549594b0

Thanks.

Kevin.

Subject: [PATCH] net/i40e: fix VF runtime queues RSS config

[ upstream commit 2da3ba7467955bce812f5f2c79c6c57859689bb6 ]

I40evf queue can not work properly with kernel pf driver for X722 vf.
Eg. when configure 8 queues pair, only 4 queues can receive packets,
and half packets will be lost if using 2 queues pair.

This issue is caused by misconfiguration of look up table, the original
code of LUT configuration did not work for X722 vf, use aq command to
setup the LUT to make it work properly.

Fixes: cea7a51c1750 ("i40evf: support RSS")
