nl80211/mac80211: Report signal average Extend nl80211 to report an exponential weighted moving average (EWMA) of the signal value. Since the signal value usually fluctuates between different packets, an average can be more useful than the value of the last packet.

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.

mac80211: give warning if building w/out rate ctrl algorithm I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't supply their own RC algorithms, this will cause ieee80211_register_hw to fail (making the driver unusable). This will tell kconfig to provide a warning if no rate control algorithms have been selected. That'll at least warn the user; users that know that their drivers supply a rate control algorithm can safely ignore the warning, and those who don't know (or who expect to be using multiple drivers) can select a default RC algorithm.

mac82011: Allow selection of minstrel_ht as default rc algorithm Allow selection of minstrel_ht as default rate control algorithm. At the moment minstrel_ht can only be requested by the driver code but not selected as default in make menuconfig. Fix this by using minstrel_ht when minstrel was selected as default and minstrel_ht is available. This change won't affect legacy devices as minstrel_ht falls back to minstrel in that case.

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.

mac80211: give warning if building w/out rate ctrl algorithm I discovered that if EMBEDDED=y, one can accidentally build a mac80211 stack and drivers w/ no rate control algorithm. For drivers like RTL8187 that don't supply their own RC algorithms, this will cause ieee80211_register_hw to fail (making the driver unusable). This will tell kconfig to provide a warning if no rate control algorithms have been selected. That'll at least warn the user; users that know that their drivers supply a rate control algorithm can safely ignore the warning, and those who don't know (or who expect to be using multiple drivers) can select a default RC algorithm.
