c89c591d19 ath6kl: rename ath6kl_wmi_qos_state_init() to _wmi_reset()
Just to make it more clear that this function is supposed to
reset wmi related variables.

cb93821a9e ath6kl: don't use cfg80211_scan_request after cfg80211_scan_done()
Use of cfg80211_scan_request is not valid after calling cfg80211_scan_done()
but ath6kl_cfg80211_scan_complete_event() was doing exactly that. Change
the function to call cfg80211_scan_done() last.

This was found during code review, I didn't see any visible problems
due to this bug.

3101edef5c ath6kl: fix missing copy of action frame contents
The wpa_supplicant was receiving incorrect frame contents in the
callback function that indicates the status of the frame transmitted.
This patch fixes a missing copy of the frame contents to a local
buffer. The local buffer keeps track of the last sent management frame.

1052261e4b ath6kl: Report unique remain-on-channel cookie values
Even though only a single concurrent remain-on-channel operation is
supported, there may be two pending remain-on-channel events (one to
indicate end of a canceled operation and another to indicate start of a
new operation). User space won't be able to distinguish these events
unless unique cookies are used.

The previous behavior resulted in wpa_supplicant getting quite
confused about the driver's offchannel state in various sequences
and this made the P2P state machine behave incorrectly. Use of
more than a single remain-on-channel cookie value fixes this.

When compiling ath6kl for ARM with device tree tree compilation fails
with errors like:

include/linux/of.h: In function 'of_property_read_u32_array':

Workaround this by including errno.h from init.c.

a24fc7c353 ath6kl: Implement support for power parameter control from userspace
In order to allow user space based control of power parameters, we use
available debugfs infrastructure. With these features user can control
power consumption by adjusting various sleep/wake up related parameters.
The feature has been added for testing purposes. All 5 parameters are
mandatory in correct order. They have to be written to the power_params
file. These are:

1) idle_period
2) no_of_pspoll
3) dtim_policy
4) tx_wakeup_policy
5) no_tx_to_wakeup

Example:

echo "200 1 0 1 1" > power_params

ef8f0eba5a ath6kl: Implement support for listen interval from userspace
In order to allow user space based control of listen interval, we use
available debugfs infrastructure. Listen interval implies how frequently
we want the WLAN chip to wake up and synchronize the beacons in case it
is in sleep mode. The command requires two parameters in the following order:

1) listen_interval_time
2) listen_interval_beacons

The user has to write the listen interval_time (in msecs) and
listen_interval_beacons (in no. of beacons) to the listen_interval file in
ath6kl debug directory.

Example:

echo "30 1" > listen_interval
