ath0 (wlan0) not working in virtulised guest with bhyve

[richard bader]

Hello,

using ath0 (and wlan) on the host is work fine. But trying the same on 
the guest does not work.

on the host freebsd 10.2 ist running
on the guest freebsd 10.3 (10.3-BETA2 FreeBSD 10.3-BETA2 #0) is running

the guest was started with:
/usr/sbin/bhyve     -c 2 -m 2048M  -A -H -P -g 0  -s 0:0,hostbridge     
-s 1:0,lpc  -s 2:0,virtio-net,tap0  -s 3:0,virtio-net,tap1  -s 
4:0,virtio-blk,wlan.bader.loc.img  -s 5,passthru,5/0/0  -l com1,stdio   
wlan

As simple experiment I try to scan for wlans using:
    root at wlan:~ #ifconfig wlan0 create wlandev ath0 && ifconfig wlan0 up 
scan
but no wlan appears.

the output of 'ifconfig wlan0' is the same as on the working host:

root at wlan:~ # ifconfig wlan0
wlan0: flags=8c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,MULTICAST> metric 
0 mtu 1500
         ether f4:f2:6d:7d:e7:52

the output for 'ssid "" channel 13 (2472 MHz 11g)' changes cyclic.

any hints to get it working?
