Hi, all

I have 3 questions about WiFi rate control algorithms.

1.  Which rate control algorithm is better?  ath9k rate control algorithm or Minstrel/Minstrel_ht rate control algorithm?
2.  How to choose rate control algorithm if both ath9k RC and Minstrel are compiled into the kernel?
3.  Is it possible to fix the rate using iw tool? How?

thanks in advance.
