Subject: [PATCH RFC v1 0/3] Support for tap user-space access with veth
interfaces

From: Sainath Grandhi <redacted>

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.

  vethtap: veth based tap driver
