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@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@wlan:~ # ifconfig wlan0
wlan0: flags=8c43<UP,BROADCAST,RUNNING,OACTIVE,SIMPLEX,MULTICAST> metric
0 mtu 1500

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