[dpdk-stable] patch 'net/i40e: fix VF overwrite PF RSS LUT for X722' has been queued to LTS release 17.11.6

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 03/13/19. So please
shout if anyone has objection.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

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")
