mac80211: make PID rate control algorithm the default
This makes the new PID TX rate control algorithm the default instead of the rc80211_simple rate control algorithm. The simple algorithm was flawed in several ways: it wasn't responsive at all and didn't age the information it was relying on properly. The PID algorithm allows us to tune characteristics such as responsiveness by adjusting parameters and was found to generally behave better. The default algorithm can be overridden to select simple instead. Which ever algorithm is the default is included as part of the mac80211 module automatically. The other algorithm (simple vs. pid) can be selected for inclusion as well. If EMBEDDED is selected then the choice is available to have no default specified and neither algorithm included in mac80211. The default algorithm can be set through a modparam. While at it, mark rc80211-simple as deprecated, and schedule it for removal. Signed-off-by: Stefano Brivio <stefano.brivio@polimi.it> Signed-off-by: John W.

318What: rc80211-simple rate control algorithm for mac80211
319When: 2.6.26
320Files: net/mac80211/rc80211-simple.c
321Why: This algorithm was provided for reference but always exhibited bad
322 responsiveness and performance and has some serious flaws. It has been
323 replaced by rc80211-pid.
