  			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.
  
  	Usage:
  		cat info

  3) FOR DRIVER CONFIGURATION
  
  regrdwr
  	This command is used to read/write the adapter register.
  
  	Usage:

  		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
  					   to ack before sending wakeup event
  
  getlog
          This command is used to get the statistics available in the station.
  	Usage:
  
  	cat getlog
  
  device_dump
  	This command is used to dump driver information and firmware memory
  	segments.
  	Usage:
