[dpdk-stable] patch 'net/bonding: fix possible null pointer reference' 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 02/07/19. 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/bonding: fix possible null pointer reference

[ upstream commit e6b8757bb72caa565d24282ad8e405f28e3a34a9 ]

In function check_for_bonded_ethdev the driver name is used without
validating the pointer references in the passed ethdev object.

Fixes: 740feaf349b1 ("ethdev: remove driver name from device private data")
