[dpdk-stable] patch 'net/i40e: fix getting RSS configuration' 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 getting RSS configuration

[ upstream commit e5584414817f3fb79655d38c728b675e4fcc1db4 ]

RSS hash configure get API (i40e_dev_rss_hash_conf_get()) didn't check
the return value of i40e_get_rss_key().
i40e_dev_rss_hash_conf_get() will return success even getting RSS hash
key failed. This patch fixes the issue.

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