Stefano Brivio c21b39aca4 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.

This options enables selection of a default rate control
algorithm to be built into the mac80211 module. Alternate
rate control algorithms might be built into the mac80211
module as well.
choice
prompt "Default rate control algorithm"
default MAC80211_RC_DEFAULT_PID
depends on MAC80211 && MAC80211_RC_DEFAULT_CHOICE
---help---
This option selects the default rate control algorithm
mac80211 will use. Note that this default can still be
overriden through the ieee80211_default_rc_algo module
parameter.
config MAC80211_RC_DEFAULT_PID
bool "PID controller based rate control algorithm"
select MAC80211_RC_PID
---help---
Select the PID controller based rate control as the
default rate control algorithm. You should choose
this unless you know what you are doing.
config MAC80211_RC_DEFAULT_SIMPLE
bool "Simple rate control algorithm"
select MAC80211_RC_SIMPLE
---help---
Select the simple rate control as the default rate
control algorithm. Note that this is a non-responsive,
dumb algorithm. You should choose the PID rate control
instead.

---help---
This option enables a TX rate control algorithm for
mac80211 that uses a PID controller to select the TX
rate.
Say Y or M unless you're sure you want to use a
different rate control algorithm.
config MAC80211_RC_SIMPLE
bool "Simple rate control algorithm (DEPRECATED)"
default n
depends on MAC80211
---help---
This option enables a very simple, non-responsive TX
rate control algorithm. This algorithm is deprecated
and will be removed from the kernel in near future.
It has been replaced by the PID algorithm.
Say N unless you know what you are doing.

depends on MAC80211
---help---
This option will enable debug tracing output for the
ieee80211 network stack.
If you are not trying to debug or develop the ieee80211
subsystem, you most likely want to say N here.
config MAC80211_HT_DEBUG
bool "Enable HT debugging output"
depends on MAC80211_DEBUG

This option enables 802.11n High Throughput features
debug tracing output.
If you are not trying to debug of develop the ieee80211

---help---
Selecting this option will cause the stack to
print a message for each frame that is handed
to the lowlevel driver for transmission. This
message includes all MAC addresses and the
frame control field.
If unsure, say N and insert the debugging code
you require into the driver you are debugging.
