Wierd issues with wifi in hostap mode in FreeBSD 11

Greetings,


I've just installed FreeBSD 11 on Soekris net5501 with the following wifi
card:


root_at_soekris:~ # dmesg |grep ath0
ath0: <Atheros 5413> mem 0xa0010000-0xa001ffff irq 15 at device 17.0 on pci0
ath0: AR5413 mac 10.5 RF5413 phy 6.1
ath0: 2GHz radio: 0x0000; 5GHz radio: 0x0063

ath0_at_pci0:0:17:0:       class=0x020000 card=0x110719b6 chip=0x001b168c
rev=0x01 hdr=0x00
    vendor     = 'Qualcomm Atheros'
    device     = 'AR5413/AR5414 Wireless Network Adapter [AR5006X(S)
802.11abg]'
    class      = network
    subclass   = ethernet


But wat is very strange for me is that I do not see ath0 device on ifconfig:


root_at_soekris:~ # ifconfig ath0
ifconfig: interface ath0 does not exist

At the same time if I crate wlan0 to list caps it works:

root_at_soekris:~ # ifconfig wlan0 create wlandev ath0
root_at_soekris:~ # ifconfig wlan0 list caps
drivercaps=4f8defc1<STA,FF,TURBOP,IBSS,PMGT,HOSTAP,AHDEMO,TXPMGT,SHSLOT,SHPREAMB

       LE,MONITOR,MBSS,WPA1,WPA2,BURST,WME,WDS,TXFRAG>
cryptocaps=1f<WEP,TKIP,AES,AES_CCM,TKIPMIC>
root_at_soekris:~ #


The issues is that when I try to start wlan0 in hostap mode - FreeBSD
freezes, unfortunatelly I cannot find my serial port cable atm and cannot
see what exactly is displayed on the console but it's a hard freeze and the
device do not reboot after it e.g. power cycle is required.


When configured from rc.conf it boots and do not freeze but still says
status: no carrier and hostapd complains that the device is not configured.

snippet from rc.conf:

cloned_interfaces="bridge0"
wlans_ath0="wlan0"
create_args_wlan0="wlanmod hostap"
ifconfig_wlan0="ssid cheffo country bg up"
ifconfig_bridge0="addm vr0 addm vr1 addm vr2 addm vr3 addm wlan0 up"
ifconfig_bridge0_alias0="inet 10.1.1.2 netmask 255.255.255.0"

I'm still with GENERIC kernel and there are no changes or custom cpu
optimizations done so far:

I have to mention that I've tried with 11-BETA2 first and there were the
same behaviour, and also I have used this soekris setup for few years with
FreeBSD 7 and 8 for a home wifi router so I do know that the hardware is
supported and OK, as it worked rock solid just before reinstalling it with
FreeBSD 11.

Any advice on how to get wifi working again?

Thanks!
