Konstantin,

I can reproduce in my office.  Here is a patch that fixed it for me.
Please update sys/net80211/ and give it a try.  Let me know right away if
you see any more problems, since they will probably harm my network, too.
Also, let me know if "no buffer space" persists or not.

BTW, it appears that we are both working on multihop wireless networks
(you mention OLSR on a KAME.net mailing list).  Have you found out yet
whether ath(4)-type hardware does a proper IBSS merge?  For atw(4),
I had to write some special code for the purpose.

Dave
