Now ath6kl is ready for splitting core code to ath6kl_core.ko module.
This also makes it possible to link both sdio and usb code to kernel
at the same time, which earlier failed miserably.

We don't need it as debug calls already have a log level and compiler
should be smart enough to optimise away the code when ath6kl debug code
is not enabled. Also it makes it easier to abstract core code to
ath6kl_core.ko.
In ath6kl_dump_registers() I had to change the debug level from ANY to IRQ
as I removed the AR_DBG_LVL_CHECK() check before calling the function.

Currently core functions are spread between various files, group all
the functions into file and rename the functions to follow the style
used elsewhere in the driver. This will make it easier to a separate core

Documentation states that the KeyMiss flag is only valid if RxFrameOK is
unset, however empirical evidence has shown that this is false.
When KeyMiss is set (and RxFrameOK is 1), the hardware passes a valid frame
which has not been decrypted. The driver then falsely marks the frame
as decrypted, and when using CCMP this corrupts the rx CCMP PN, leading
to connection hangs.

* A new APSD power save queue is added in the station structure.
* When a station has APSD capability and goes to power save, the frame
designated to the station will be buffered in APSD queue.
* When the host receives a frame which the firmware marked as trigger,
host delivers the buffered frame from the APSD power save queue.
Number of frames to deliver is decided by MAX SP length.
* When a station moves from sleep to awake state, all frames buffered
in APSD power save queue are sent to the firmware.
* When a station is disconnected, all frames bufferes in APSD power save
queue are dropped.
* When the host queues the first frame to the APSD queue or removes the
last frame from the APSD queue, it is indicated to the firmware using
WMI_AP_APSD_BUFFERED_TRAFFIC_CMD.

This patch addresses a few problems with the commit:
"ath6kl: Implement support for listen interval from userspace"
* The debugfs file required for reading/writing the listen interval
wasn't created. Fix this.
* The interface index was being hardcoded to zero. Fix this.
* Two separate parameters, "listen_interval_time and listen_interval_beacons"
were being used. This fails to work as expected because the FW assigns
higher precedence to "listen_interval_beacons" and "listen_interval_time"
ends up being never used at all.
To handle this, fix the host driver to exclusively use listen interval
based on units of beacon intervals.
To set the listen interval, a user would now do something like this:
echo "10" > /sys/kernel/debug/ieee80211/*/ath6kl/listen_interval

The commit "ath9k: Fix invalid noisefloor reading due to channel update"
preserves the current channel noisefloor readings before updating
channel type at the same channel index. It is also updating the curchan
pointer. As survey updation is also referring curchan pointer to fetch
the appropriate index, which might leads to invalid memory access. This
patch partially reverts the change and stores the noise floor history
buffer before updating channel type w/o updating curchan.

AR9003 chips read tx status from ring buffer whose max number of
status descriptor is mininal compared to max number of tx buffers.
On a stress condition, it can be easily overflown which might cause
false tx hung detection. Though increasing number of max status

chip resets.
