COMPILING DRIVER
==================================================================================
Prepare: 

	AX88796B Linux Driver Source.
	Linux Kernel source code.
	Cross-Compiler.

Getting Start:

	1.Extracting the AX88796B source file by executing the following command.
		[root@localhost]# tar jxvf ax88796b-arm-linux2.6.tar.bz2

	2.Edit the makefile to specifie the path of target platform Linux Kernel source.
		example for kernel 2.6.x:
			KDIR = /work/linux-2.6.x
		example for kernel 2.4.x:
			KDIR = /work/linux-2.4.x/include

	3.For kernel 2.4.x , you need to specify the path of Cross-Compiler
          example
		CROSS_COMPILE = /usr/local/arm/<versions>/bin/arm-linux-

	4.Executing 'make' command to compiler AX88796B Driver.

	5.If the compilation well, the ax88796b.ko(ax88796b.o) will be created under
	  the current directory.


==================================================================================
DRIVER PARAMETERS
==================================================================================
The following parameters can be set when using insmod.
EX: [root@localhost ax88796b]# insmod  ax88796.ko  mem=0x08000000

	mem=0xNNNNNNNN 
		specifies the physical base address that AX88796B can be accessed.
		Default value '0x08000000'.

	irq=N
		specifies the irq number. Default value '0x27'.

	media=N
		Set media mode (0=auto, 1=100full, 2=100half, 3=10full, 4=10half).
		Default is 0

	example: insmod ax88796b.ko(ax88796b.o) media=1 mem=0x08000000 irq=0x27
