* Removed unused WOW_MAX_FILTER_LISTS macro.
* Removed empty ath6kl_wmi_get_wow_list_event_rx() function.
List of configured WOW patterns are maintained in CFG layer
itself. No need to have this function in ath6kl to get
configured WOW pattern list. It can added later if we need
it for debugging.

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.

There is no point in unconditionally converting the bssinfo header
to the old version since only the new header is being used and the
driver can as well read the values from it when needed. Leaving out
the conversion saves some extra memory copying.
In addition, use the calculated "rssi" value snr - 95 dBm to get the
proper value in cfg80211 BSS table (i.e., something that more or less
matches with the value used in STA info).

This cleans up the connect event parsing by defining a union in
struct wmi_connect_event to match with the three possible sets of
fields that the target uses depending on which type of connect
event is being indicated. In addition, two AP cases are now
separated from ath6kl_connect_event() so that correct field names
can be used to make it actually possible to understand what the
code is doing.
The bug hiding in the previous mess was in parsing the AID incorrectly
when processing the new station connecting event in AP mode. The fix
here for that is also fixing TIM updates for PS buffering to use the
correct AID.

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:
