[dpdk-stable] patch 'net/mlx5: fix release of Rx queue object' has been queued to LTS release 17.11.7

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 07/27/19. 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. 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.

Yongseok

Subject: [PATCH] net/mlx5: fix release of Rx queue object

[ backported from upstream commit 10cfa5f2d4affef0561e5245aad4bc69b29cd671 ]

Function mlx5_rx_intr_disable() calls mlx5_rxq_ibv_get() and performs
some actions on the returned rxq_ibv.
It doesn't release the rxq_ibv when all is completed with success.

This patch adds call to mlx5_rxq_ibv_release() where it's missing.

Fixes: 09cb5b581762 ("net/mlx5: separate DPDK from verbs Rx queue objects")
