Hello,

I managed to send a serie of patches with git send-email. It should be
received in few minutes on the list. General comments on this patch
serie :

Before this patch, I had the following issues:
- - laptop was freezing a lot on module load/unload or when the
interface was brought up
- - on some case, I got WPDMA not ready errors that i could only fix by
rebooting
- - TX / RX padding was not correct, so it was preventing a correct
authentication and DHCP exchange
- - I was not getting an interrupt each time a packet was transmitted on
the air, this was either causing TX queue begin full quickly or error
messages about "missed" packets
- - TX status reporting was wrong and the driver was stick to 6 Mbits in
802.11a

With this patch serie, here is the result :
- - laptop has not freeze for 24 hours
- - laptop has been running an iperf with a constant 20 Mbits throughput
for like 8 hours
- - TX/RX padding has been checked using a monitor interface and
injecting all kinds of packets
- - an interrupt occurs each time a packet has been transmitted (there
is also another interrupt each time the DMA transfer has been done)
- - minstrel has now switch to use 54 Mbits
- - STA WPA2 HW encryption is working
- - NetworkManager is happy as well
- - minor fix in intializing the SHARED_KEY_MODE_TABLE
- - minor fix in the fallback rate table

What could be improved / still not working :
- - 802.11n is not working (in fact 802.11n frames are NOT even received!)
- - minstrel is now a bit stick to 54 Mbits too much (even in poor radio
condition)
- - TX status reporting could be improved in the still-to-occur case
where an interrupt or a TX status is missed
- - RX/TX alignment needs to be checked

Those patches applies on 2.6.30-wl. I tried them on 2.6.31-wl and my
laptop was freezing all the time (might not be caused by rt2800pci,
who knows...).
I used the rt2x00 git tree.

Comments are highly welcome since the I wanted to release the patch as
early as possible to get feedback.

Regards,
Benoit
