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 drivers/net/Kconfig | 28 + 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 | 27 +- drivers/net/ipvlan/ipvtap.c | 241 ++++++++ drivers/net/macvlan.c | 2 +- drivers/net/macvtap.c | 1229 ++---------------------------------- drivers/net/tap.c | 1268 ++++++++++++++++++++++++++++++++++++++ drivers/vhost/Kconfig | 2 +- drivers/vhost/net.c | 3 +- include/linux/if_macvlan.h | 17 +- include/linux/if_tap.h | 75 +++ 14 files changed, 1698 insertions(+), 1209 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
