[dpdk-stable] patch 'net/virtio: remove useless check on mempool' has been queued to LTS release 18.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/19. 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/7bdd00ecf5e811ea56bd7a6824329e2d6bacff59

Thanks.

Kevin Traynor

Subject: [PATCH] net/virtio: remove useless check on mempool

[ upstream commit 711b07ce6e2d6b2ac674fad909b5e2f7249bc7a3 ]

This .rx_queue_setup devop is called after ethdev already dereferenced
the mempool pointer.
No need to check and we can remove this rte_exit.

Fixes: 48cec290a3d2 ("net/virtio: move queue configure code to proper place")
