I'm having trouble using the lagg driver with wpa_supplicant. When I
boot with this standard configuration, my wifi works fine:
> # Normal config.
> wlans_iwn0="wlan0"
> ifconfig_wlan0="WPA DHCP"
> ifconfig_em0="DHCP"
But when I boot with a lagg configuration, wpa_supplicant can't connect.
> # Lagg config.
> ifconfig_em0="up"
> ifconfig_iwn0="ether 3c:97:0e:46:70:ca"
> wlans_iwn0="wlan0"
> ifconfig_wlan0="WPA"
> cloned_interfaces="lagg0"
> ifconfig_lagg0="laggproto failover laggport em0 laggport wlan0 DHCP"
The system spends a full 5 minutes during boot trying to send DHCP
requests before finally giving up. After boot, ifconfig shows that
wlan0 has the right ssid, but the status is 'no carrier':
> wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
> ether 3c:97:0e:46:70:ca
> nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

> deftxkey UNDEF txpower 30 bmiss 10 scanvalid 60 protmode CTS
> ampdulimit 8k -amsdutx amsdurx shortgi -stbc wme roaming MANUAL
> groups: wlan
If I then manually kill wpa_supplicant and restart it with the same
command, it works fine.

This is my hardware:

I know I had this working at one point on 10.2-RELEASE, but recently
I've tried both 11.0-BETA2 and 12-CURRENT and get this behavior. Any
advice for debugging?
