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 09/03/19. 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/ddddaf1a3a361afe33d078cc0da1d04630b19320
Thanks.

Subject: [PATCH] net/mlx5: fix crash on null operation
[ upstream commit 8f0fa0c0adf5dac18641af89143eabea0662f5a2 ]
mlx5 implements mlx5_flow_null_drv_ops to be used when a specific
flow typei/driver is not available or invalid.
This routines return error without modifying the rte_flow_error
parameter passed to them which causes testpmd, for example, to crash.
This commit addresses the issue by modifying the rte_flow_error
parameter in theses routines.
Fixes: 0c76d1c9a18d ("net/mlx5: add abstraction for multiple flow drivers")
Fixes: 684dafe795d0 ("net/mlx5: add flow query abstraction interface")
