I am also interested in being able to change the
contention window values, so I was wondering how long
before this madwifi version is released?
Also...I am not very familiar with how QoS is
implemented, but I thought that the contention window
was implemented in hardware. Does that mean that any
wireless card using the Atheros chip set provides an
interface to change that value? I've been looking at
other drivers (ipw2100 and prism54), and they don't
seem to support changing the contention window, so
that's why I'm wondering if this capability is limited
to specific wireless cards.
Thanks for the help,

There two type of cards. The Software Programmable Design has no real
firmware written to the card. All features are driven from the host. That=
is regarded quite dangerous from regulation authorities so most vendors
are distributing this part as binary only.
