$ insmod dummy0
$ ifconfig dummy0 0.0.0.0 -broadcast -arp up
$ ifconfig dummy0
dummy0    Link encap:Ethernet  HWaddr 00:00:00:00:00:00  
          UP BROADCAST RUNNING NOARP  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
$ ip li sh dummy0
4: dummy0: <BROADCAST,NOARP,UP> mtu 1500 qdisc noqueue 
    link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff

It works just fine... on an ethernet interface as well.  (Doing this
part of the process of getting pppoe up and running...)

Cheers
