Does any one have status or any info on BCM43231 USB drivers?

I've received my WNA3100, 0846:9020 (maybe BCM43231, can't confirm).

It works with ndiswrapper and bcmwlhigh6, I can scan and even connect
to my WPA2 network.

Unfortunately I've no idea what hardware is this. I've dumped
ndiswrapper USB operations but they don't tell me a single thing.
Initialization is represented by only ~1000 lines in dumps and I've
connected in next ~1500 lines of USB dump. I've been using "usbmon" to
dump traffic.

The evidence points to some kind of Broadcom chip. The USB data base says that 
an ID of "0846:9020" is a "WNA3100(v1) Wireless-N 300 [Broadcom BCM43231]". In 
addition, the Windows driver name of bcmwlhigh6 indicates a BroadCoM WL driver 
of some sort. Given the relatively small amount of initialization traffic, it 
must be a fullmac device that likely does not need external firmware.

I remember seeing some mail about the Broadcom guys working on a Linux driver 
for a USB fullmac device. Is this the one? (I added Arend to the Cc.)
