As tap is a virtual device, there's no physical way a link can be cut. However, it has an associated kernel netdevice and possibly a remote netdevice too. These netdevices link status may change outside of the DPDK scope, through an external command such as: ip link set dev tapX down This commit implements link status notification through netlink.
