I think the DAD code is broken anyway... It doesn't make certain the
query packet is actually sent, for instance.
On the laptop I have, ne2 times out for the first few packets sent,
then recovers and works normally. DAD reports "no duplicates found"
long before it starts to reliably transmit/receive...
