On ng_bridge, I turned : off promiscuous mode on the wi interface and things still worked. : Performance also went back up to pre bridging levels. I have no : idea why and haven't had time to play more. 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.
