I was at a party tonight with Todd Miller, who lives in the area and
did a lot of the OpenBSD hostap work. He tells me that if you are in
promiscuous mode, that hostap performance falls to heck (1Mbps), but
if you take it out of promiscuous mode performance returns. One of
the changes in OpenBSD that I have on my to look at list is related to
this.
