Since this is now in our public API, I'm wondering whether we shouldn't
make the buflen longer. 6 bytes is fine with wired ethernet, but I'm
not sure its sufficient for all network device types  in general.

eg, my wmaster0 device has a rather longer hardware address

wmaster0  Link encap:UNSPEC  HWaddr 00-13-02-B9-F9-D3-F4-1F-00-00-00-00-00-00-00-00  
          UP BROADCAST RUNNING MULTICAST  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:1000 
          RX bytes:0 (0.0 b)  TX bytes:0 (0.0 b)

Daniel
