It did work with mine (a WS2950), confirmed by counters on the
cisco side, and concurent ttcp tests.
But I had to specify the wm interface last, so that
the SIOCSIFADDR is done on an interface that can handle it.

So maybe SIOCSIFADDR should be pushed back to if_ethersubr.c ?
But I wonder if this could be done with the same ioctls as the
ones used by ifconfig. This way code change would be limited to
agr.
