Libertas driver on the OLPC board

[Chris Kavanagh]

Hello,

I'm working on an entirely different platform both hardware and software.  
However, it seems that OLPC and myself are both using Marvell based WiFi 
radios.  I have been battling with a problem for sometime now and haven't 
received a whole lot of support from Marvell.  I noticed on a Libertas group 
that the OLPC driver was recieving a status code of 4 on associations - I am 
also seeing this with my system.

I've been leaning towards the idea that this might be more then just an 
incorrect status code but rather serious issue in the firmware.  In fact if 
I dump the entire contents of my association response buffer recieved from 
the firmware via the AP, I actually see data from my association request 
buffer that was just previously downloaded to the card.  As if one buffer is 
being copied over the other in the firmware.

It took me a while to see this because the buffer recieved from the firmware 
almost looks good.  For example:

The first 4 ushorts seem to look fine (correct response code, reasonable 
size, sequence number and command result), so the driver begins processing 
the rest of the data (the association data).  The Cap Info looks reasonable, 
the associationID is fine (same as what's "sniffed" in the air) but the 
status code is 0x0004.  It wasn't until I started looking at the rest of the 
buffer that I noticed my WEP key in place text was now part of my 
association response IE elements.  Obviously something that wasn't 
transmitted by the AP :)

This concerns me because on the edge of a network with pour signal strength 
this seems to happen often as per retry's and occationally the firmware 
stops responding to commands altogether.

Has anyone had any luck in tracking down this "StatusCode == 4" issue?

In advance, thank you very much for you help,
Chris
