[dpdk-stable] patch 'net/i40e: fix VF overwrite PF RSS LUT for X722' has been queued to LTS release 18.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS 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 02/14/19. 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.

Thanks.

Kevin Traynor

Subject: [PATCH] net/i40e: fix VF overwrite PF RSS LUT for X722

[ upstream commit 1d4b2b4966bbb219afd2d7072ffba51f3a3067a5 ]

i40e_aq_set_rss_lut should set register according
to the vsi->type. if not, VF may overwrite the rigister
of PF.
Note, only X722 is impacted, since flag I40E_FLAG_RSS_AQ_CAPABLE
is only enabled on X722.

Fixes: d0a349409bd7 ("i40e: support AQ based RSS config")
