virtio-net: enable TSO/checksum offloads for Q-in-Q vlans
[ Upstream commit 2836b4f224d4fd7d1a2b23c3eecaf0f0ae199a74 ]
Since virtio does not provide it's own ndo_features_check handler,
TSO, and now checksum offload, are disabled for stacked vlans.
Re-enable the support and let the host take care of it. This
restores/improves Guest-to-Guest performance over Q-in-Q vlans.
