Subject: [PATCHv3 0/7] Refactor macvtap to re-use tap functionality by other virtual intefaces

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
