Apologies for following up to myself, but there haven't been any replies
that I've seen so far.

Continued googling has led me to a mailing list archive where Theo De
Raadt says that wireless interfaces only bridge correctly in hostap mode.

What isn't clear to me is whether this means that I cannot do what I'm
trying to do, which is to use this OpenBSD box to bridge from one wired
zone to another wired zone. It appears that I would have to be able to
attach rtw0 to my other access point, but how to do that in hostap mode
is not clear to me. Any further explanation would be welcome.
