└─>Simple rate control algorithm (DEPRECATED)
In linux kernel since version 2.6.25 (release Date: 2008-04-16)  
This option enables a very simple, non-responsive TX
rate control algorithm. This algorithm is deprecated
and will be removed from the kernel in the near future.
It has been replaced by the PID algorithm.

Say N unless you know what you are doing.
