[PULL 12/14] virtio-net: Advertise UDP tunnel GSO support by default

["Michael S. Tsirkin" <mst@redhat.com>]

From: Paolo Abeni <pabeni@redhat.com>

Allow bidirectional aggregated traffic for UDP encapsulated flows.

Add the needed compatibility entries to avoid migration issues
vs older QEMU instances.
