From: Sainath Grandhi

Tap character devices can be implemented on other virtual interfaces like
ipvlan, similar to macvtap. Source code for tap functionality in macvtap
can be re-used for this purpose.

This patch series splits macvtap source into two modules, macvtap and tap.
This patch series also includes a patch for implementing tap character
device driver based on the IP-VLAN network interface, called ipvtap.

These patches are tested on x86 platform.

Sainath Grandhi (7):
tap: Refactoring macvtap.c
tap: Renaming tap related APIs, data structures, macros
tap: Tap character device creation/destroy API
tap: Abstract type of virtual interface from tap implementation
tap: Extending tap device create/destroy APIs
tap: tap as an independent module
ipvtap: IP-VLAN based tap driver
