[TUNTAP]: Allow setting the linktype of the tap device from userspace
Currently tun/tap only supports the EN10MB ARP type. For use with wireless and other networking types it should be possible to set the ARP type via an ioctl. Patch v2: Included check that the tap interface is down before changing the link type out from underneath it Signed-off-by: Mike Kershaw <dragorn@kismetwireless.net> Signed-off-by: David S.
