Kalle Valo b0fc7c1a64 ath6kl: fix regression in ath6kl_upload_board_file()
My patch 24fc32b3 ("ath6kl: add ath6kl_bmi_write_hi32()") caused a regression
in ath6kl_upload_board_file() and the board_address variable was not
properly initialised in some cases:

ath6kl/init.c:1068:6: warning: ‘board_address’ may be used uninitialized
in this function

Most likely this broke ar6004 support but I can't test that right now.

Raja Mani 8f46fccd6c ath6kl: Maintain the listen interval per VIF specific
Firmware has the option to support the listen interval
per vif specific. Fix this.

Listen interval can be set by the TUs or by the number
of beacons. Current code enables the user to configure
the listen interval in the unit of 'number of beacons'
using debugfs entry "listen_interval". Going forward,
we need to alter the listen interval in the unit of TUs
to get good power numbers while going to WOW suspend/resume.

Allowing the user to change the listen interval in
the unit of "number of beacons"  in debugfs and changing
listen interval in wow suspend/resume in the unit of
time (TUs) would lead us to confuse.

This patch make sures the listen interval is changed only
in the unit of time (TUs).

Below two scenarios are taken care in this patch which helped
to fix the firmware crash during wow suspend/resume.

* TX operation (ctrl tx and data tx) has to be controlled based
  on suspend state. i.e, with respect to WOW mode, control packets
  are allowed to send from the host until the suspend state goes
  ATH6KL_STATE_WOW and the data packets are allowed until WOW
  suspend operation starts.

* Similarly, wow resume is NOT allowed if WOW suspend is in progress.

It gives flexibility to the user to define suspend policy
when the suspend mode is set to WOW and the device is in
disconnected state at the time of suspend.

New module parameter wow_mode is added to get the choice
from the user. This parameter is valid only if the module
parameter suspend_mode is set to WOW.

To force WOW in connected state and cut power
in disconnected state:
  suspend_mode=0x3 wow_mode=0x1

To force WOW in connected state and deep sleep
in disconnected state (this is also the default wow_mode):
   suspend_mode=0x3 wow_mode=0x2

If there is no value specified to wow_mode during insmod,
deep sleep mode will be tried in the disconnected state.

On Access Point mode, when transmitting a packet, if the destination
station is in powersave mode, we abort transmitting the packet to the
device queue, but we do not reclaim the allocated memory.  Given enough
packets, we can go in a state where there is no packet on the device
queue, but we think the device has no memory left, so no packet gets
transmitted, connections breaks and the AP stops working.

This undo the allocation done in the TX path when the station is in

Raja Mani 4480bb5936 ath6kl: Lower SDIO pad drive strength for hw2.1.1 board
Without this change, SDIO shuts down due to CRC error during
data communication to the firmware in some of the platform.
for example, scan request issued to the firmware doesn't
return scan completed events and cause the socket interface
to always return -16 (device busy).

SDIO pad drive strength should be reduced for hw2.1.1 board
to avoid such errors.

Vasanthakumar Thiagarajan 13423c3119 ath6kl: Make foreground scan a deterministic one
This makes the device get into scan state as soon as a
scan request is received, instead of blocking the scan
request till the traffic comes down. It is  necessary
for the deterministic foreground scan particularly when
having multiple vif operating where, if the scan is non-
deterministic, scan on one interface will not start
as long as there are traffic on the other interface. This
change passes 50 msec as foreground scan interval to fix this.

Vasanthakumar Thiagarajan 5378f244b6 ath6kl: Fix memory leak of rx packets in endpoint 0
htc_packet and htc_packet->buf_start are separately allocated
for endpoint 0. This is different for other endpoints where
packets are allocated as skb where htc_packet is skb->head
and they are freed properly. Free htc_packet and htc_packet->buf_start
separatly for endpoint 0.

Vasanthakumar Thiagarajan bd5b5ac287 ath6kl: Make sure to allocate rx buffers after the endpoint connection
Rx buffers should be allocated for control and best effort endpoints only
after the enpoints connection is esablished. But this is done before the
endpoint connection is complete, we don't even the control and BE endpoints
that time. Move the buffer allocation after endpoint connection is over,
after ath6kl_init_hw_start(). Found in review, never seen any real issue
with this.
