Disable ratecontrol for ATH9K_HTC

[Pieter Robyns]

Hi all,

I've created a fork of the firmware intended for experimental /
research functionality such as fixing the data rate, disabling carrier
sensing, convenient printing, etc. The repository is located here:
https://github.com/rpp0/open-ath9k-htc-firmware.

This modified firmware fixes the rate to a certain hardcoded value out
of the box - no driver modification required. However, if you use my
driver as well (https://github.com/rpp0/linux), there are some
additional features which you can use, such as printing to dmesg over
USB instead of over UART, setting the fixed rate with a userspace
program, setting register values, etc.

The driver uses netlink for communication with userspace instead of
debugfs, because for some features I needed bidirectional
communication. Currently you can only use the driver with one device
at a time. I'll try to add some documentation and an example program
that explains how to use the netlink interface today.

Hopefully, this is useful to somebody!


Kind regards,
Pieter

For that it would be great to disable the rate control of the ATH9K_HTC driver module (use a fixed bitrate). The iw command doesn't seem to work and as far as I understand, the ATH9k_HTC isn't using the minstrel algorithm located in MAC80211 module.
