Add timer based auto deep sleep feature in libertas driver which can be
configured using iwconfig command. This is tested on SD8688, SD8686 cards
with firmware versions 10.38.1.p25, 9.70.4.p0 respectively on 32-bit and 64-bit
platforms. Tests have been done for USB/CS cards to make sure that the patch
won't break USB/CS code. We didn't test the if_spi driver.

SD8688 is a WLAN/Bluetooth combo chip and both functions are supported
in a single firmware image. FUNC_INIT and FUNC_SHUTDOWN commands are
implemented to utilize the multiple function feature.
When SD8688 card is inserted, the firmware image should be downloaded
only once through either WLAN function (Libertas driver) or Bluetooth
function (Bluetooth driver).
This patch adds function init/shutdown for SD8688 WLAN function only.

This patch is based on a patch from Shailendra Govardhan and Brian Cavagnolo.
It extends the MESH_CONFIG command to configure non-volatile parameters on

This patch only implements the driver/firmware interface.

This patch moves re-works the implementation of event subscription
via debugfs. For this:
* it tells cmd.c and cmdresp.c about CMD_802_11_SUBSCRIBE_EVENT
* removes lots of low-level cmd stuff from debugfs.c
* create unified functions to read/write snr, rssi, bcnmiss and
failcount
* introduces #define's for subscription event bitmask values
* add a function to search for a specific element in an IE
(a.k.a. TLV)
* add a function to find out the size of the TLV. This is needed
because lbs_prepare_and_send_command() has an argument for a
data buffer, but not for it's lengths and TLVs can be, by
definition, vary in size.
* fix a bug where it was not possible to disable an event

Driver support for the monitor mode support that will be available in the next
OLPC 'bleeding edge' Marvell firmware release (most likely, 5.110.16.p2).
To activate monitor mode,
echo mode > /sys/class/net/{ethX,mshX}/device/libertas_rtap
where mode is the hex mask that specifies which frames to sniff (in short, 0x1
for data, 0x2 for all management but beacons, 0x4 for beacons). Any non zero
mode will activate the monitor mode, inhibiting transmission in ethX and mshX
interfaces and routing all the incoming traffic to a new rtapX interface that
will output the packets in 802.11+radiotap headers format.

They contains the same info: the firmware command opcode and, when the
firmware sends back a result, the command opcode ORed with 0x8000.
Having the same data twice in the source code is redundant and can lead to
errors (e.g. if you update or delete only one instance). This patch removed
all CMD_RET_xxx definitions and introduces a simple CMD_RET() macro.

With firmware 5.220.11.p5, this allows to specify the anycast addresses the
device will listen to.
The anycast address range is C0:27:C0:27:C0:XX where XX goes from 00 to 1F (or
0 to 31 in dec). The value to write on anycast_mask will specify which
addresses the device listens to. Bits in a 32 bit int are numbered from 0
(least significative bit) to 31. A specific address ending in YY will be
listened to if bit YY in the value is set to one.
Examples:
0x00000000 : do not listen to any anycast address
0xFFFFFFFF : listen to every anycast address from :00 to :1F
0x00000013 : listen to anycast addresses :00, :01 and :04
