[PULL 22/33] net/vhost-vdpa: Whitelist virtio-net GSO for shadow virtqueue

Posted by Michael S. Tsirkin 1 month, 2 weeks ago

From: Eugenio Pérez <eperezma@redhat.com>

Even if it is deprecated by the VirtIO standard it does not affect the
layout of the queue, or introduces new operations. So Shadow Virtqueue
can handle it just fine.

Tested with OVS DPDK and VDUSE.
