    Subject[PATCHv2 0/7] Refactor macvtap to re-use tap functionality by other virtual intefaces
    Date
    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
