Johannes Berg 4b475898ec mac80211: better rate control algorithm selection
This patch changes mac80211's Kconfig/Makefile to:
 * select between the PID and the SIMPLE rate control
   algorithm as default
 * always allow tri-state for the rate control algorithms,
   building those that are selected 'y' into the mac80211
   module (if that is a module, otherwise all into the kernel)
 * force the default rate control algorithm to be built into
   mac80211

It also makes both rate control algorithms proper modules again
with MODULE_LICENSE etc.

Only if EMBEDDED is the user allowed to select "NONE" as default
which will cause no algorithm to be selected, this will work
only when the driver brings one itself (e.g. iwlwifi drivers).

default MAC80211_RC_DEFAULT_PID
---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 if different algorithms are available.
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.
config MAC80211_RC_DEFAULT_NONE
bool "No default algorithm"
depends on EMBEDDED
help
Selecting this option will select no default algorithm
and allow you to not build any. Do not choose this
option unless you know your driver comes with another
suitable algorithm.

tristate "PID controller based rate control algorithm"
---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
tristate "Simple rate control algorithm (DEPRECATED)"
---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 the near future.
It has been replaced by the PID algorithm.
Say N unless you know what you are doing.

config MAC80211_DEBUG
bool "Enable debugging output"
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
---help---
This option enables 802.11n High Throughput features
debug tracing output.
If you are not trying to debug of develop the ieee80211
subsystem, you most likely want to say N here.

---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.
