===============================================================================
			U S E R  M A N U A L

1) FOR DRIVER INSTALL

	a) Copy sd8787.bin to /lib/firmware/mrvl/ directory,
	   create the directory if it doesn't exist.
	b) Install WLAN driver,
		insmod mwifiex.ko
	c) Uninstall WLAN driver,
		ifconfig mlanX down
		rmmod mwifiex


2) FOR DRIVER CONFIGURATION AND INFO
	The configurations can be done either using the 'iw' user space
	utility or debugfs.

	a) 'iw' utility commands

	Following are some useful iw commands:-

iw dev mlan0 scan

	This command will trigger a scan.
	The command will then display the scan table entries

iw dev mlan0 connect -w <SSID> [<freq in MHz>] [<bssid>] [key 0:abcde d:1123456789a]
	The above command can be used to connect to an AP with a particular SSID.
	Ap's operating frequency can be specified or even the bssid. If the AP is using
	WEP encryption, wep keys can be specified in the command.
	Note: Every time before connecting to an AP scan command (iw dev mlan0 scan) should be used by user.

iw dev mlan0 disconnect
	This command will be used to disconnect from an AP.


iw dev mlan0 ibss join <SSID> <freq in MHz> [fixed-freq] [fixed-bssid] [key 0:abcde]
	The command will be used to join or create an ibss. Optionally, operating frequency,
	bssid and the security related parameters can be specified while joining/creating
	and ibss.

iw dev mlan0 ibss leave
	The command will be used to leave an ibss network.

iw dev mlan0 link
	The command will be used to get the connection status. The command will return parameters
	such as SSID, operating frequency, rx/tx packets, signal strength, tx bitrate.

	Apart from the iw utility all standard configurations using the 'iwconfig' utility are also supported.

	b) Debugfs interface

	The debugfs interface can be used for configurations and for getting
	some useful information from the driver.
	The section below explains the configurations that can be
	done.

	Mount debugfs to /debugfs mount point:

		mkdir /debugfs
		mount -t debugfs debugfs /debugfs

	The information is provided in /debugfs/mwifiex/mlanX/:

iw reg set <country code>
	The command will be used to change the regulatory domain.

iw reg get
	The command will be used to get current regulatory domain.

info
	This command is used to get driver info.

3) FOR DRIVER CONFIGURATION

regrdwr
	This command is used to read/write the adapter register.

	Usage:
		echo " <type> <offset> [value]" > regrdwr
		cat regrdwr

	where the parameters are,
		<type>:     1:MAC/SOC, 2:BBP, 3:RF, 4:PMIC, 5:CAU
		<offset>:   offset of register
		[value]:    value to be written

	Examples:
		echo "1 0xa060" > regrdwr           : Read the MAC register
		echo "1 0xa060 0x12" > regrdwr      : Write the MAC register
		echo "1 0xa794 0x80000000" > regrdwr
		                                    : Write 0x80000000 to MAC register
rdeeprom
	This command is used to read the EEPROM contents of the card.

	Usage:
		echo "<offset> <length>" > rdeeprom
		cat rdeeprom

	where the parameters are,
		<offset>:   multiples of 4
		<length>:   4-20, multiples of 4

	Example:
		echo "0 20" > rdeeprom      : Read 20 bytes of EEPROM data from offset 0

hscfg
	This command is used to debug/simulate host sleep feature using
	different configuration parameters.

	Usage:
		echo "<condition> [GPIO# [gap]]]" > hscfg
		cat hscfg

	where the parameters are,
		<condition>: bit 0 = 1   -- broadcast data
			     bit 1 = 1   -- unicast data
			     bit 2 = 1   -- mac event
			     bit 3 = 1   -- multicast data
		[GPIO#]: pin number of GPIO used to wakeup the host.
			 GPIO pin# (e.g. 0-7) or 0xff (interface, e.g. SDIO
			 will be used instead).
		[gap]:   the gap in milliseconds between wakeup signal and
			 wakeup event or 0xff for special setting (host
			 acknowledge required) when GPIO is used to wakeup host.

	Examples:
		echo "-1" > hscfg        : Cancel host sleep mode
		echo "3" > hscfg         : Broadcast and unicast data;
					   Use GPIO and gap set previously
		echo "2 3" > hscfg       : Unicast data and GPIO 3;
					   Use gap set previously
		echo "2 1 160" > hscfg   : Unicast data, GPIO 1 and gap 160 ms
		echo "2 1 0xff" > hscfg  : Unicast data, GPIO 1; Wait for host
