From: Sainath Grandhi <sainath.gran...@intel.com> 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.
