88fecd092e mac80211: remove "bcn_int" and "capab" scan results info
These bits were dead code before "mac80211: Remove local->scan_flags"
(commit 6681dd3fd0e4d36a4547415853e83411baa7b705) and probably should
have been removed as part of that commit.

e38bad4766 mac80211: make ieee80211_iterate_active_interfaces not need rtnl
Interface iteration in mac80211 can be done without holding any
locks because I converted it to RCU. Initially, I thought this
wouldn't be needed for ieee80211_iterate_active_interfaces but
it's turning out that multi-BSS AP support can be much simpler
in a driver if ieee80211_iterate_active_interfaces can be called
without holding locks. This converts it to use RCU, it adds a
requirement that the callback it invokes cannot sleep.

76ee65bfaa mac80211: restructuring data Rx handlers
This patch restructures the Rx handlers chain by incorporating previously
handlers ieee80211_rx_h_802_1x_pae and ieee80211_rx_h_drop_unencrypted
into ieee80211_rx_h_data, already in 802.3 form. this scheme follows more
precisely after the IEEE802.11 data plane archituecture, and will prevent
code duplication to IEEE8021.11n A-MSDU handler.

added function:
 - ieee80211_data_to_8023: transfering 802.11 data frames to 802.3 frame
 - ieee80211_deliver_skb: delivering the 802.3 frames to upper stack
eliminated handlers:
 - ieee80211_rx_h_drop_unencrypted: now function ieee80211_drop_unencrypted
 - ieee80211_rx_h_802_1x_pae: now function ieee80211_802_1x_pae
changed handlers:
 - ieee80211_rx_h_data: now contains calls to four above function

ece8edddf0 mac80211: hardware scan rework
The scan code in mac80211 makes the software scan assumption in various
places. For example, we stop the Tx queue during a software scan so that
all the Tx packets will be queued by the stack. We also drop frames not
related to scan in the software scan process. But these are not true for
hardware scan.

Some wireless hardwares (for example iwl3945/4965) has the ability to
perform the whole scan process by hardware and/or firmware. The hardware
scan is relative powerful in that it tries to maintain normal network
traffic while doing a scan in the background. Some drivers (i.e iwlwifi)
do provide a way to tune the hardware scan parameters (for example if the
STA is associated, what's the max time could the STA leave from the
associated channel, how long the scans get suspended after returning to
the service channel, etc). But basically this is transparent to the
stack. mac80211 should not stop Tx queues or drop Rx packets during a
hardware scan.

This patch resolves the above problem by spliting the current scan
indicator local->sta_scanning into local->sta_sw_scanning and
local->sta_hw_scanning. It then changes the scan related code to be aware
of hardware scan or software scan in various places. With this patch,
iwlwifi performs much better in the scan-while-associated condition and
disable_hw_scan=1 should never be required.

dabeb344f5 mac80211: provide interface iterator for drivers

a10605e599 mac80211: free ifsta->extra_ie and clear IEEE80211_STA_PRIVACY_INVOKED
I'm not sure if this is best choice, someone might have better
solutions. But this patch fixed the connection problem when switching
from a WPA enabled AP (using wpa_supplicant) to an open AP (using
iwconfig). The root cause is when we connect to a WPA enabled AP,
wpa_supplicant sets the ifsta->extra_ie thru SIOCSIWGENIE. But if we
stop wpa_supplicant and connect to an open AP with iwconfig, there is
no way to clear the extra_ie so that mac80211 keeps connecting with that.

Someone could argue wpa_supplicant should clear the extra_ie during
its shutdown. But mac80211 should also handle the unexpected shutdown
case (ie. killall -9 wpa_supplicant).

Make "decrypt failed" and "have no key" debugging messages compile

A typical example is an enviornment where multiple SSIDs are using a
single BSSID but with different protection schemes or different keys

ac71c691e6 mac80211: make simple rate control algorithm built-in
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.)

87ae9afdca cleanup asm/scatterlist.h includes
Not architecture specific code should not #include <asm/scatterlist.h>.

This patch therefore either replaces them with
#include <linux/scatterlist.h> or simply removes them if they were
unused.

ddd68587d0 [PATCH] mac80211: fix printk warning on 64-bit
My AID message patch introduced a warning on 64-bit machines because ~
extends to unsigned long:

| net/mac80211/ieee80211_sta.c: In function ‘ieee80211_rx_mgmt_assoc_resp’:
| net/mac80211/ieee80211_sta.c:1187: warning: format ‘%d’ expects type ‘int’, but argument 7 has type ‘long unsigned int’

This fixes it by explicitly casting the result to u16 (which 'aid' is).

48225709be [PATCH] mac80211: Fix SSID matching in AP selection
The length of the SSID desired should also be compared in addition to
the memcmp of the SSIDs.

Thanks to Andrea Merello <andreamrl@tiscali.it> for finding this issue.

117636092a [PATCH] Fix breakage after SG cleanups
Commits

  58b053e4ce ("Update arch/ to use sg helpers")
  45711f1af6 ("[SG] Update drivers to use sg helpers")
  fa05f1286b ("Update net/ to use sg helpers")

converted many files to use the scatter gather helpers without ensuring
that the necessary headerfile <linux/scatterlist> is included.  This
happened to work for ia64, powerpc, sparc64 and x86 because they
happened to drag in that file via their <asm/dma-mapping.h>.

On most of the others this probably broke.

Instead of increasing the header file spider web I choose to include
<linux/scatterlist.h> directly into the affectes files.
