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.

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.)

Removes the management interface since it is only required
for hostapd/userspace MLME, will not be in the final tree
at least in this form and hostapd/userspace MLME currently
do not work against this tree anyway.

This makes mac80211 print out the wiphy name instead of the

I think these can go with rate control just as well and it makes
ieee80211.c more readable.

Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).
Here is a short excerpt of the semantic patch performing
this transformation:
