[dpdk-stable] patch 'net/bnxt: fix crash in xstats get' has been queued to LTS release 18.11.6

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/17/19. 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/48d9b60c0ad1c25e0c36b7bfc4075580b10bc88d

Thanks.

Kevin.

Subject: [PATCH] net/bnxt: fix crash in xstats get

[ upstream commit 063e59ddd28e3a147107366ddba9fb8baeeebc31 ]

We would hit a segfault in bnxt_dev_xstats_get_op() if xstats argument
is NULL, Check if the argument is NULL and return appropriately.

Fixes: bfb9c2260be2 ("net/bnxt: support xstats get/reset")
