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.

Subject: [PATCH] net/virtio: fix rewriting LSC flag

[ backported from upstream commit f229eb41eeecfc121600379046c7f11680739f1a ]

The LSC flag is decided according to if VIRTIO_NET_F_STATUS feature
is negotiated. Copy the PCI info after the judgement will rewrite
the correct result.

Fixes: 198ab33677c9 ("net/virtio: move device initialization in a function")
