This patchset adds a tap device driver for veth virtual network interface.
With this implementation, tap character interface can be added only to the
peer veth interface. Adding tap interface to veth is for usecases that forwards
packets between host and VMs. This eliminates the need for an additional
software bridge. This can be extended to create both the peer interfaces as
tap interfaces. These patches are a step in that direction.

Interesting, plan to add vhost support for this? And we can enable
zerocopy without any worries I think.
Thanks
