Okay, one last attempt. :-P

If we add:

   case ARPHDR_NONE:
	memset(hw, 0, sizeof(struct hardware));
	break;

Right before the "default:" statement in the get_hw_addr() hack that I
posted earlier it might work. This means that if for some reason there
is no address we'll just proceed without it.

Cheers,
