Hi,
FYI, your patch has been queued to stable release 18.08.1
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/18/18. 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. 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.
Kevin Traynor

Subject: [PATCH] net/mlx5: fix validation of Rx queue number
[ upstream commit 8dd569abad0802f2e5adb0a4ac2483a07555ac89 ]
Function mlx5_ctrl_flow_vlan() is used to set the rss rule in
MLX5 PMD, using priv->reta_idx_n as number of Rx queues.
This number is passed to mlx5_flow_validate_action_rss(), which
attempts to access the Rx queues at priv->rxqs.
In case priv->rxqs_n is 0, priv->rxqs is empty, and
mlx5_flow_validate_action_rss() will crash with segmentation fault.
priv->reta_idx_n can never be 0, even if priv->rxqs_n is set to 0.
But when priv->rxqs_n is set to 0, setting the rss rule is invalid.
This patch updates mlx5_ctrl_flow_vlan(), if priv->rxqs_n is 0 the
function will fail with EINVAL errno.
Fixes: 8086cf08b2f0 ("net/mlx5: handle RSS hash configuration in RSS flow")
