It'd be interesting to see if that fixes the reported problems, no?

Unfortunately my laptop was recently stolen so I'm short a NetBSD wireless
client to test with.  OS X does not _appear_ to have the reported issue on
my wireless infrastructure, at least, but I am watching the traffic from
a different host on a mirror port on my switch so I can't tell whether
my APs are in fact sending the DAD packets back to the originating wireless
client by unicast or not. :-/
