For my research, i want to disable backoff as well as physical and virtual carrier sense. I have currently set cwmin and cwmax to 0 and AIFS to 1 (imitate beacon) to disable the backoff. To test this i guess ad-hoc mode is suitable. I am looking for insights into which modes and rates are supported over ath9k chipsets and how multiple antennas will have impact over my experimentation.

The problems is adhoc is limited to only legacy rate and the HT patch for IBSS is not yet officially merged.
