Jouni Malinen 551185ca0a ath6kl: Update BSS information after connection
Since we may end up using a dummy BSS entry when roaming, allow one Beacon
frame -based bssinfo from the current BSS to be processed prior to starting
to filter all bssinfo events. This allows cfg80211 BSS table to be filled
with proper data in the roaming case where the full Beacon data may not
have been present at the time of roamed event.

Jouni Malinen 82e14f56f7 ath6kl: Remove unnecessary bssinfo event header conversion
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).

Jouni Malinen 1aaa8c7469 ath6kl: Replace internal node table with cfg80211 BSS table
The internal node table in ath6kl was not really used for any useful
purpose. It was just used to collect scan results during a scan and then
provide them in a burst to cfg80211 at the completion of the scan. There
is no point in doing this since cfg80211 is perfectly capable of
maintaining the BSS table and the BSS inform messages are sent in
separate function calls anyway.

This provides more complete information in the cfg80211 BSS table since
this allows Beacon and Probe Response frames to be distinguished and IEs
from them reported separately.

Jouni Malinen 572e27c00c ath6kl: Fix AP mode connect event parsing and TIM updates
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.

Kalle Valo bdcd817079 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:
