The iproute patch for the rtnl_link API. For simple devices
that take no configuration like dummy or ifb no further
changes are needed.

Example:

Create dummy device:

# ip link add type dummy

Show device:

# ip -d link list dummy0

9: dummy0: <BROADCAST,NOARP> mtu 1500 qdisc noop
    link/ether ae:9a:0c:8e:f5:e1 brd ff:ff:ff:ff:ff:ff
    dummy

Delete device again:

# ip link delete dummy0
