Where do I change QoS parameters

[Rafael Ordanini]

Hello folks,

i've googling a lot these days to find a solution for my problem. I also
found a lot of answers and sugestion but none worked for me.

I'm trying to change some parameters as *cw_min, cw_max, txop*,...relationated
with wmm.

I took the *Cw_min* and *Cw_max* to test change the values. First of all, it
seems that these kind of parameter isn't defined at the a specific
module/driver (mine is ar9170, based on otus).

I saw those parameters at */.../net/mac802.11/rc80211_minstrel.c *, and of
course, tried to change it. Do not worked. Actually, when I did compile,
thousand errors appeared.

Someone knows where do I change that parameters? At least cw (or acw's)
parameter?

Best Regards,
