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. 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 drivers/net/Kconfig | 26 + drivers/net/Makefile | 2 + drivers/net/ipvlan/Makefile | 1 + drivers/net/ipvlan/ipvlan.h | 7 + drivers/net/ipvlan/ipvlan_core.c | 5 +- drivers/net/ipvlan/ipvlan_main.c | 37 +- drivers/net/ipvlan/ipvtap.c | 238 +++++++ drivers/net/macvlan.c | 2 +- drivers/net/macvtap.c | 1227 ++---------------------------------- drivers/net/tap.c | 1276 ++++++++++++++++++++++++++++++++++++++ drivers/vhost/net.c | 3 +- include/linux/if_macvlan.h | 4 +- include/linux/if_tap.h | 63 ++ 13 files changed, 1691 insertions(+), 1200 deletions(-) create mode 100644 drivers/net/ipvlan/ipvtap.c create mode 100644 drivers/net/tap.c create mode 100644 include/linux/if_tap.h -- 2.7.4
