Hi,

FYI, your patch has been queued to stable release 17.05.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/24/17. So please
shout if anyone has objections.

Thanks.

Subject: [PATCH] net/virtio: do not claim to support LRO

[ upstream commit 701a64622c2653c0736042d2f790081db79afdc7 ]

The current virtio supports Transmit Segmentation Offload, but
does not really support Large Receive Offload. The driver was confusing
the two offloads.

Fixes: 86d59b21468a ("net/virtio: support LRO")
