I'm trying to get a lagg interface with failover to work with bfe0
and wlan0. The master port is bfe0, with failover to wlan0. The
wlan0 interface is ath0.
I can get both wlan0 and bfe0 to work independently without being
lagg devices, but only bfe0 works when wlan0 and bfe0 are in a
lagg interface. In other words, when I pull the plug on bfe0, it
does not failover to wlan0.
The system is a 1 month old -current (i386) that has been pretty
stable and I'm using something like this in /etc/rc.conf:
wlans_ath0=wlan0
ifconfig_wlan0="ssid my_ssid \
wepkey 1:0xblah1 wepkey 2:0xblah2 \
wepkey 3:0xblah3 wepkey 4:0xblah4 \
weptxkey 1 authmode shared"
ifconfig_bfe0="up"
cloned_interfaces="lagg0"
ifconfig_lagg0="laggproto failover laggport bfe0 laggport wlan0"
ifconfig_lagg0_alias0="inet 10.0.0.7 netmask 0xffffff00"
$ ifconfig -a

Note that wlan0 is not associated as it would normally be when not
configured as a lagg device. If I uplug the cable from bfe0, then I
get:

Any ideas?
