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.

[ upstream commit 65600813884cf018358dc09c032c78f8f5f5a83b ]

by one. See also ixgbe process.
