bcm4322 success (WPA2)!

[Tom Gundersen]

Hi Rafał,

I also have a bcm4322 chip, which works with WPA2 using 2.6.38-rc5.

This is the only thing I had to do to make it work.

I'm seeing about the same here.

Furthermore, I get about 5% packet loss when pinging my wireless
router (with no other traffic).

iwconfig says that my rate is 11 Mb/s, but since I expected it to be
54, I figured this might be wrong, so I tried
% iwconfig wlan0 rate 11M

This appears to solve the problem completely! I have not seen any more
errors and my packet loss is 0%. (The download speed is still
suboptimal, but I read that you already have some patches for that, so
I'll just wait for when they are posted.)

Thanks for making this work! (It is infinitely better than the wl
driver...). If ever you need some testing of new patches related to my
card, let me know.

Cheers,

Tom
