[dpdk-stable] patch 'net/cxgbe: skip parsing match items with no spec' 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 01/11/19. 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/cxgbe: skip parsing match items with no spec

[ upstream commit cadce5ee8aec5236d06474a94db0ba0ec6a48321 ]

Skip parsing pattern match items that have no spec. This fixes NULL
dereference when accessing their non-existent spec.
