Hi all,
first of all, if linux-wireless isn't the correct list for this, then
please point me into the right direction.
I got a new laptop from my employer which includes a b43 wireless
card, that isn't working with current git kernel (actually it is the
rt2x00 branch from Ivo).
Here are the messages I get from 'dmesg'.
b43-phy1: Broadcom 4322 WLAN found (core revision 16)
b43-phy1 ERROR: FOUND UNSUPPORTED PHY (Analog 8, Type 4, Revision 4)
b43: probe of ssb0:0 failed with error -95
Broadcom 43xx driver loaded [ Features: PML, Firmware-ID: FW13 ]
I'm available to test drivers, patches, git kernels, the whole lot.
(I'm going to use this laptop to work on rt2x00, although the
available antennas aren't quite compatible, as they are for 3G module)

yes, it even is a half-height minipci-express card, the first one I've
seen so far.

11n is doomed on Linux :(

Oh, it depends on the configuration -- maybe they used a cheaper device
with fewer chains.

Don't hold your breath -- nobody's working on it. I also really want it
working, but since nobody seems even interested in writing the driver,
we've halted the reverse engineering effort.

This is an 11n phy.

There's nothing available beyond what you have.

Great, an 11n device with only two antennas (they are usually three).

Bummer, I guess I'll have to wait then.

Thanks for the info.

11n does not require three antennas. It really depends on the number
of streams you have and the chain configuration. As a matter of fact
you can use 11n with 1 stream and only use the lower MCS rates.

I have a vested interest in getting the LP PHY (type 5) code done as I
have one of those devices. As a result, I'm deliberately not working
on the RE for the 11n PHYs until the LP PHY code is working. If that
was not clear enough, then let me restate it: "If you want code for
Broadcom devices with ID 4322 and higher, you are going to have to do
the LP code first."
