[Yuanhan Liu]

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 RSS hash result for flows

[ upstream commit 36ba0c0097c6aaf969fe520f91352e772a143904 ]

Flows redirected to a specific queue do not have a valid RSS hash result
and the related mbuf flag must not be set.

Fixes: ecf60761fc2a ("net/mlx5: return RSS hash result in mbuf")
