cfg80211 layer provides user defined wow parameters like Filter options, Patterns,
Pattern's mask, etc via "struct cfg80211_wowlan *wow" to suspend function.
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.

This is to reset hif layer for powering down hw.

In preparation for cutting down power from the chip on the fly.

That way we htc level debug messages can be removed from hif files. Also
add few new messages and remove useless debug message about using
synchrous irq processing (we don't support anything else).

Power save is enabled during ath6kl init. But when user space disables power
save, the system will go into suspend with power save disabled. The ath6kl
driver will now explicitly enable power save prior to entering suspend and
restore its previous setting upon resume

For now this is implemented so that if host supports power is kept in
the chip. If that's not supported, an error is returned and sdio stack
will remove the device during suspend.

Define a hook in ath6kl_hif_ops for hif scatter gather mechanism.
When virtual scatter gather is used, call the respective function
directly.

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:
