This is still a problem with wm in NetBSD 5.0.
[I hadn't particularly noticed the issue till now with our machines with wm
(probably because the switch ports are set to do "portfast" spanning tree)
but on looking I see that there is a three second or so break going into
or out of promisc. However we now have some machines with wm interfaces
that are configured as 802.1q trunks and if you put those into promisc
there is a 35 second disruption]
