Don't think it will help for this specific problem, but this patch fixes
alignment problem (especially seen on ARM, Russell:-)). Sending as a text
attachment, as my setup is known to mangle tabs...

Status: NEW
Severity: normal
Owner: rmk@xxxxxxxxxxxxxxxx
Submitter: hadmut@xxxxxxxxxx

Aironet 340 PCMCIA card
Software Environment:
Debian
Problem Description:
The system was working well with
2.4.x and 2.6.x kernels up to 2.6.6.
After upgrade to 2.6.7 the WLAN does n
not work anymore: There is no error message,
no warning, everything looks fine, except
for the fact that traffic is not possible.
Maybe a WEP problem?
