Re: implementing multiple BSSID addresses for different VAPs, or 'why was the flag called bssid again?'
Hi, It doesn't surprise me that the devd and rc.conf scripts seem to be clashing. I'd very much like to see this fixed. Would someone please take a crack at it?

Well, the following in rc.conf wlans_ath0="wlan0 wlan2" create_args_wlan0="bssid wlanmode hostap country DE authmode wpa ssid COYOTE" ifconfig_wlan0="ssid COYOTE mode 11g pureg up" create_args_wlan2="bssid wlanmode hostap country DE authmode wpa ssid COYOTE_GUEST" ifconfig_wlan2="ssid COYOTE_GUEST mode 11g pureg up" Does not quite work, I'm left with: (from dmesg) Setting hostname: coyote.spoerlein.net. bridge0: Ethernet address: 02:ac:6e:56:db:00 Created clone interfaces: bridge0. wlan0: Ethernet address: 68:a3:c4:51:44:99 wlan2: Ethernet address: 6e:a3:c4:51:44:99 ifconfig: SIOCS80211: Device busy ath0: stuck beacon; resetting (bmiss count 4) (not that there's no echo for creating wlan devices, that should maybe be added?)

Is it possible that there is a timing issue involved and doing it manually works better than when the startup scripts run through this? I've now got this working version that seems to be solid and comes up during boot w/o manual intervention. /etc/rc.conf: wlans_ath0="wlan0 wlan
implementing multiple BSSID addresses for different VAPs, or 'why was the flag called bssid again?'
So, I finally (!) figured out how this address cloning crap works. In if_ath.c, there's assign_address(). It, yes, assigns addresses. If the hardware supports the bssid mask field and the clone flag is set, it sets up multiple addresses. This works great for up to 4 MACs. We have to modify it to support more than 4 MAC addresses per NIC. .. but, how do you set the clone flag? The ifconfig manpage has two entries for 'bssid'. * the first is when you 'create' a VAP. It's passed as an arguement during create, but before wlanmode. It doesn't take an option. * the second is for setting the BSS ID for the VAP. It _does_ take an option (the MAC.) If you try this, it fails: * ifconfig wlan11 create wlandev ath0 wlanmode hostap ssid 'foo_2' bssid If you try this, it works: * ifconfig wlan11 create wlandev ath0 bssid wlanomde hostap ssid 'foo_2' So, if you run multi-VAP, and you want to use WPA on all of the VAPs, please try using 'bssid' as above and ensure you get multiple MAC addresses. This should make things behave much, much better. If it doesn't then we have bigger problems.
