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: NStefano Brivio <stefano.brivio@polimi.it> Signed-off-by: NJohn W.

Move some code out of rc80211_simple since it's probably needed for all rate selection algorithms, and fix iwlwifi accordingly. While at it, clean up the rate_control_get_rate() interface.

Fix inappropriate memory freeing in case of requested rate_control_ops was not found. In this case the list head entity is going to be accidentally wasted.

Previously, mac80211 would allow registering the same rate control algorithm twice. This is a programming error in the registration and should not happen; additionally the second version could never be selected. Disallow this and warn about it.

Too frequently people do not have module autoloading enabled or fail to install the rate control module correctly, hence their hardware probing fails due to no rate control algorithm being available. This makes the 'simple' algorithm built into the mac80211 module unless EMBEDDED is enabled in which case it can be disabled (eg. if the wanted driver requires another rate control algorithm.)
