thank you for this hint. By printing the values (see below), I found out that the MAC implementation always use EDCA with best effort as the default traffic class!

Betreff: Re: ath9k-based Mesh uses EDCA or DCF
Try take a look on the ath9k_conf_tx in ath9k/main.c.
The setting of aifs, cw_min , cw_max and txop may make sense to you.

Unfortunately, I could not find any information on this issue in the corresponding debugfs files of ath9k (I am running a small mesh testbed). I would greatly appreciate any hints on this topic.
