From some testing that I've done, it appears that SIOCSIFADDR is not supported under io-pkt.  Is this correct?

I was trying to use ioctl(fd,SIOCSIFADDR,foo) to set the mac address of my ethernet interface (my hardware supports this
.. matter of fact demands it in order to keep the MAC addresses unique).

What is the preferred method for accomplishing this (i.e. getting the equivalent of an SIOCSIFADDR down to my driver's 
if_ioctl function)??

Thanks!!
