[PATCHv6 0/7] Refactor macvtap to re-use tap functionality by other virtual intefaces

[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
