[dpdk-stable] patch 'net/i40e: fix get RSS conf' 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 02/07/19. 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 get RSS conf

[ upstream commit 286a809c99c033f895c6b08c2af4b741f17ae29b ]

rte_eth_dev_rss_hash_conf_get API doesn't force 'rss_conf.rss_key'
to be not NULL, so rss_key = NULL should be alllowed in i40e
driver.

Fixes: 16321de09396 ("ethdev: allow to get RSS hash functions and key")
