-			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

-			 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.
