macvtap support for libvirt -- helper code This part adds the helper code to setup and tear down macvtap devices using direct communication with the device driver via netlink sockets. The rather short messages received from the netlink layer are now written into a dynamically allocated buffer * src/util/macvtap.h src/util/macvtap.c: provides the new module * po/POTFILES.in: the module contains translated strings

macvtap IFF_VNET_HDR configuration This patch sets or unsets the IFF_VNET_HDR flag depending on what device is used in the VM. The manipulation of the flag is done in the open function and is only fatal if the IFF_VNET_HDR flag could not be cleared although it has to be (or if an ioctl generally fails). In that case the macvtap tap is closed again and the macvtap interface torn. * src/qemu/qemu_conf.c src/qemu/qemu_conf.h: pass qemuCmdFlags to qemudPhysIfaceConnect() * src/util/macvtap.c src/util/macvtap.h: add vnet_hdr boolean to openMacvtapTap(), and private function configMacvtapTap() * src/qemu/qemu_driver.c: add extra qemuCmdFlags when calling qemudPhysIfaceConnect()
