Upgrade b43 and mac80211.

This also temporarly disables hostapd support for mac80211, as hostapd needs patches to compile against latest mac80211.
Will do that in a seperate patch.

Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)

The actually used mode is selectable through the module
parameter "pio". If the module parameter is pio=0, DMA is used.
Otherwise PIO is used. DMA is default.
If unsure, choose this option.

select B43_DMA
---help---
Only include Direct Memory Access (DMA).
This reduces the size of the driver module, by omitting the PIO code.
config B43_PIO_MODE
bool "PIO (Programmed I/O) only"
select B43_PIO
---help---
Only include Programmed I/O (PIO).
This reduces the size of the driver module, by omitting the DMA code.
Please note that PIO transfers are slow (compared to DMA).
Also note that not all devices of the 43xx series support PIO.
The 4306 (Apple Airport Extreme and others) supports PIO, while
the 4318 is known to _not_ support PIO.
Only use PIO, if DMA does not work for you.

Subject: mac80211: add beacon configuration via cfg80211
This patch implements the cfg80211 hooks for configuring beaconing
on an access point interface in mac80211. While doing so, it fixes
a number of races that could badly crash the machine when the
beacon is changed while being requested by the driver.
Signed-off-by: Johannes Berg <johannes@sipsolutions.net>
---
The dtim_count field should possibly also be part of the beacon
structure, but the possible race there doesn't really matter,
worst thing is that one beacon will be sent with a wrong dtim
count if (and only if) userspace changes the dtim period during
operation.

Subject: cfg80211/nl80211: implement station attribute retrieval
After a station is added to the kernel's structures, userspace
has to be able to retrieve statistics about that station, especially
whether the station was idle and how much bytes were transferred
to and from it. This adds the necessary code to nl80211.

/* This is an implementation of a TX rate control algorithm that uses a PID
* controller. Given a target failed frames rate, the controller decides about
* TX rate changes to meet the target failed frames rate.
*
* The controller basically computes the following:
*
* adj = CP * err + CI * err_avg + CD * (err - last_err) * (1 + sharpening)
*
* where
* adj adjustment value that is used to switch TX rate (see below)
* err current error: target vs. current failed frames percentage
* last_err last error
* err_avg average (i.e. poor man's integral) of recent errors
* sharpening non-zero when fast response is needed (i.e. right after
* association or no frames sent for a long time), heading
* to zero over time
* CP Proportional coefficient
* CI Integral coefficient
* CD Derivative coefficient
*
* CP, CI, CD are subject to careful tuning.
*
* The integral component uses a exponential moving average approach instead of
* an actual sliding window. The advantage is that we don't need to keep an
* array of the last N error values and computation is easier.
*
* Once we have the adj value, we map it to a rate by means of a learning
* algorithm. This algorithm keeps the state of the percentual failed frames
* difference between rates. The behaviour of the lowest available rate is kept
* as a reference value, and every time we switch between two rates, we compute
* the difference between the failed frames each rate exhibited. By doing so,
* we compare behaviours which different rates exhibited in adjacent timeslices,
* thus the comparison is minimally affected by external conditions. This
* difference gets propagated to the whole set of measurements, so that the
* reference is always the same. Periodically, we normalize this set so that
* recent events weigh the most. By comparing the adj value with this set, we
* avoid pejorative switches to lower rates and allow for switches to higher
* rates if they behaved well.
*
* Note that for the computations we use a fixed-point representation to avoid
* floating point arithmetic. Hence, all values are shifted left by
* RC_PID_ARITH_SHIFT.
*/
/* Adjust the rate while ensuring that we won't switch to a lower rate if it
* exhibited a worse failed frames behaviour and we'll choose the highest rate
* whose failed frames behaviour is not worse than the one of the original rate

* This regulatory domain control implementation is known to be incomplete

*
* For now, drivers wishing to control which channels are and aren't available

* - set the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag
* - continue to include *ALL* possible channels in the modes registered
* through ieee80211_register_hwmode()
* - for each allowable ieee80211_channel structure registered in the above
* call, set the flag member to some meaningful value such as
* IEEE80211_CHAN_W_SCAN | IEEE80211_CHAN_W_ACTIVE_SCAN |
* IEEE80211_CHAN_W_IBSS.
* - leave flag as 0 for non-allowable channels
*
* The usual implementation is for a driver to read a device EEPROM to
* determine which regulatory domain it should be operating under, then
* looking up the allowable channels in a driver-local table, then performing

/*
* This regulatory domain control implementation is highly incomplete, it
* only exists for the purpose of not regressing mac80211.
*
* For now, drivers can restrict the set of allowed channels by either
* not registering those channels or setting the IEEE80211_CHAN_DISABLED
* flag; that flag will only be *set* by this code, never *cleared.
*
* The usual implementation is for a driver to read a device EEPROM to
* determine which regulatory domain it should be operating under, then
* looking up the allowable channels in a driver-local table and finally
* registering those channels in the wiphy structure.
*
* Alternatively, drivers that trust the regulatory domain control here
* will register a complete set of capabilities and the control code
* will restrict the set by setting the IEEE80211_CHAN_* flags.
