ath6kl: Move and rename ath6kl_cleanup_vif function
Rename ath6kl_cleanup_vif function as 'ath6kl_cfg80211_vif_stop'
which is the more appropriate name considering the functionality
of the module and vif specific cleanup is actually done by
ath6kl_cfg80211_vif_cleanup. Also move it to cfg80211.c.
Also make ath6kl_cfg80211_sta_bmiss_enhance as static function.
This addresses a FIXME/TODO.

ath6kl: rework scheduled scan
This patch reflects changes in the firmware scheduled scan
implementation to behave better in cases with multiple concurrent vifs.
Major changes:
- scheduled scan filters and state are now programmed per-vif.
- decouple scheduled scan from host sleep.
To maintain graceful failure with old firmwares, a new firmware
capability bit is introduced: ATH6KL_FW_CAPABILITY_SCHED_SCAN_V2.
ath6kl simply won't advertise scheduled scan to cfg80211 if the
SCHED_SCAN_V2 is not supported.
Since firmwares from here on out won't support the previous implicit API
for scheduled scan (set WoW filters and host sleep), bump the firmware
API to protect old drivers.
Unfortunately, due to firmware RAM constraints ath6kl still cannot
expect a scan complete event at the end of a scheduled scan results
cycle, so the sched_scan_timer is retained.

ath6kl: implement scheduled scan
ath6kl firmware supports scheduled scan functionality with the wow ssid
filter. But the firmware does not send any events after scan results
so I had to add a timer which notifies about new scan results.
Sched scan needs firmware version 3.2.0.6 or later. If firmware doesn't
support sched scan the driver will not enable the feature.

Right now, this wowlan parameter is not handled in __ath6kl_cfg80211_suspend func.
This parameter has to be passed to HIF layer, So that it can be passed back to
ath6kl's cfg interface layer when WOW mode is selected.
In case of deep sleep and cut power mode, it's not handled.

ath6kl: add aborted parameter to ath6kl_cfg80211_scan_complete_event()
Currently it takes an error code as status, but what we really want to
tell is if the scan was aborted or not.
Also fix a bug where we were comparing firmware scan status values
with kernel error codes, which is obviously wrong. This meant
that ath6kl didn't detect when firmware informed about failed scans. I
doubt that this fix doesn't make any difference in practise but it
still needs to be fixed. This is fixed by adding an enum for the success
status code and checking for that.

Add ath6kl cleaned up driver
Last May we started working on cleaning up ath6kl driver which is
currently in staging. The work has happened in a separate
ath6kl-cleanup tree:
http://git.kernel.org/?p=linux/kernel/git/kvalo/ath6kl-cleanup.git;a=summary
After over 1100 (!) patches we have now reached a state where I would
like to start discussing about pushing the driver to the wireless
trees and replacing the staging driver.
The driver is now a lot smaller and looks like a proper Linux driver.
The size of the driver (measured with simple wc -l) dropped from 49
kLOC to 18 kLOC and the number of the .c and .h files dropped from 107
to 22. Most importantly the number of subdirectories reduced from 26
to zero :)
There are two remaining checkpatch warnings in the driver which we
decided to omit for now:
drivers/net/wireless/ath/ath6kl/debug.c:31:
WARNING: printk() should include KERN_ facility level
drivers/net/wireless/ath/ath6kl/sdio.c:527:
WARNING: msleep < 20ms can sleep for up to 20ms;
see Documentation/timers/timers-howto.txt
The driver has endian annotations for all the hardware specific
structures and there are no sparse errors. Unfortunately I don't have
any big endian hardware to test that right now.
We have been testing the driver both on x86 and arm platforms. The
code is also compiled with sparc and parisc cross compilers.
Notable missing features compared to the current staging driver are:
o HCI over SDIO support
o nl80211 testmode
o firmware logging
o suspend support
Testmode, firmware logging and suspend support will be added soon. HCI
over SDIO support will be more difficult as the HCI driver needs to
share code with the wifi driver. This is something we need to research
more.
Also I want to point out the changes I did for signed endian support.
As I wasn't able to find any support for signed endian annotations I
decided to follow what NTFS has done and added my own. Grep for sle16
and sle32, especially from wmi.h.
Various people have been working on the cleanup, the hall of
fame based on number of patches is:
