Kernel Crash on starting hostapd

[ravin goyal]

Hi Rafal

As you have mentioned I have looked up for my wifi hardware , it is
supported by brcmfmac.

I am using Ampak AP6212 wifi hardware which is listed as part of
brcmfmac following link: http://linux-sunxi.org/Wifi

I have inserted the brcmfmac module manually using modprobe but my
wlan0 interface is linked with bcmdhd when I removed it I don't see
wlan0 in ifconfig
and when i re-insert it again and starts hostapd, it starts but it
didn't broadcast the ssid and afterwards I tried to re-insert bcmdhd
with op_mode=2 and starts hostapd again and it displayed the ssid this
time (which i am currenly doing)

It means hostapd is directly communicating with bcmdhd ,what does it
has to do with brcmfmac
Moreover on the given link they didn't provide the name of the driver
ap6212 is using. but it follows brcmfmac mainline kernel.

Regards
Ravin
