veth: extend features to support tunneling
While investigating on a recent vxlan regression, I found veth
was using a zero features set for vxlan tunnels.
We have to segment GSO frames, copy the payload, and do the checksum.
This patch brings a ~200% performance increase
We probably have to add hw_enc_features support
on other virtual devices.
