Hi Rafał,

I confirm Larry's feedbacks. I tried both on a 32bit and a 64bit architectures (the first is frodo), and it works. I too see only CCK packets. On 64bit arch (Atom) it works but when I try to unload the module I get this

[ 1117.516031] unregister_netdevice: waiting for wlan1 to become free. Usage count = 1

and the device is never release (by who?). I have to reboot.

I'm using two cards, one reports

[  311.439406] b43-phy0: Broadcom 4321 WLAN found (core revision 12)
[  311.480046] b43-phy0 debug: Found PHY: Analog 5, Type 4, Revision 2
[  311.480075] b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2055, Revision 4

The other (an Apple original card) reports

[   82.726931] b43-phy0: Broadcom 4321 WLAN found (core revision 11)
[   82.768030] b43-phy0 debug: Found PHY: Analog 5, Type 4, Revision 1
[   82.768062] b43-phy0 debug: Found Radio: Manuf 0x17F, Version 0x2055, Revision 4

Thanks,
-Francesco
