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. SVN-Revision: 10466

-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
+ * target. While at it, check that the new rate is valid. */

+/*
+ * API definition :
+ * --------------
+ * See <linux/wireless.h> for details of the APIs and the rest.
+ *
+ * History :
+ * -------
+ *
+ * v1 - 5.12.01 - Jean II
+ * o Created this file.
+ *
+ * v2 - 13.12.01 - Jean II
+ * o Move /proc/net/wireless stuff from net/core/dev.c to here
+ * o Make Wireless Extension IOCTLs go through here
+ * o Added iw_handler handling ;-)
+ * o Added standard ioctl description
+ * o Initial dumb commit strategy based on orinoco.c
+ *
+ * v3 - 19.12.01 - Jean II
+ * o Make sure we don't go out of standard_ioctl[] in ioctl_standard_call
+ * o Add event dispatcher function
+ * o Add event description
+ * o Propagate events as rtnetlink IFLA_WIRELESS option
+ * o Generate event on selected SET requests
+ *
+ * v4 - 18.04.02 - Jean II
+ * o Fix stupid off by one in iw_ioctl_description : IW_ESSID_MAX_SIZE + 1
+ *
+ * v5 - 21.06.02 - Jean II
+ * o Add IW_PRIV_TYPE_ADDR in priv_type_size (+cleanup)
+ * o Reshuffle IW_HEADER_TYPE_XXX to map IW_PRIV_TYPE_XXX changes
+ * o Add IWEVCUSTOM for driver specific event/scanning token
+ * o Turn on WE_STRICT_WRITE by default + kernel warning
+ * o Fix WE_STRICT_WRITE in ioctl_export_private() (32 => iw_num)
+ * o Fix off-by-one in test (extra_size <= IFNAMSIZ)
+ *
+ * v6 - 9.01.03 - Jean II
+ * o Add common spy support : iw_handler_set_spy(), wireless_spy_update()
+ * o Add enhanced spy support : iw_handler_set_thrspy() and event.
+ * o Add WIRELESS_EXT version display in /proc/net/wireless
+ *
+ * v6 - 18.06.04 - Jean II
+ * o Change get_spydata() method for added safety
+ * o Remove spy #ifdef, they are always on -> cleaner code
+ * o Allow any size GET request if user specifies length > max
+ * and if request has IW_DESCR_FLAG_NOMAX flag or is SIOCGIWPRIV
+ * o Start migrating get_wireless_stats to struct iw_handler_def
+ * o Add wmb() in iw_handler_set_spy() for non-coherent archs/cpus
+ * Based on patch from Pavel Roskin <proski@gnu.org> :
+ * o Fix kernel data leak to user space in private handler handling
+ *
+ * v7 - 18.3.05 - Jean II
+ * o Remove (struct iw_point *)->pointer from events and streams
+ * o Remove spy_offset from struct iw_handler_def
+ * o Start deprecating dev->get_wireless_stats, output a warning
+ * o If IW_QUAL_DBM is set, show dBm values in /proc/net/wireless
+ * o Don't loose INVALID/DBM flags when clearing UPDATED flags (iwstats)
+ *
+ * v8 - 17.02.06 - Jean II
+ * o RtNetlink requests support (SET/GET)
+ *
+ * v8b - 03.08.06 - Herbert Xu
+ * o Fix Wireless Event locking issues.
+ *
+ * v9 - 14.3.06 - Jean II
+ * o Change length in ESSID and NICK to strlen() instead of strlen()+1
+ * o Make standard_ioctl_num and standard_event_num unsigned
+ * o Remove (struct net_device *)->get_wireless_stats()
+ *
+ * v10 - 16.3.07 - Jean II
+ * o Prevent leaking of kernel space in stream on 64 bits.
