Hi,

FYI, your patch has been queued to stable release 16.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable
yet. It will be pushed if I get no objections before 01/28/17.
So please shout if anyone has objections.

Note 16.11 is a LTS release. v16.11.1 is planned to be released
shortly (about 2-3 weeks) after v17.02.

Thanks.

Subject: [PATCH] net/mlx5: fix leak when starvation occurs

[ upstream commit fe5fe3820e504380f4abd15f839f63dd6e5c508f ]

The list of segments to free was wrongly manipulated ending by only freeing
the first segment instead of freeing all of them.  The last one still
belongs to the NIC and thus should not be freed.
