RTL8180 Linux Driver version 1.4

  - Support Client mode for either infrastructure or adhoc mode
  - Support AP mode

RTL8180 Linux Driver version 1.5

  - Turn on Dynamic Carrier Sense Function.


===============================================================================================
< Component >
The driver is composed of several parts:
    (1)source code
         driver module initialization and interface between rtl8180 driver and system call.
         r8180_pci_init.c    driver module initialization and register/unregister network device
         r8180_pci_init.h    include file
         r8180_if.c          interface between rtl8180 driver and system call
         r8180_if.h          include file
         r8180_type.h        type definition for rtl8180 driver
         r8180_export.h      exported function name from rtl8180 driver

    (2)object code
         rtl8180 driver
         priv_part.o         rtl8180 driver object code

    (3)Default driver
         rtl8180_24x.o       default driver module compiled in kernel 2.4.18.

    (4)Makefile
         PLEASE SPECIFY INCLUDEPATH CORRECTLY ACCORDING TO YOUR LINUX ENVIRONMENT.
         FOR EXAMPLE, " INCLUDEPATH=-I /usr/src/linux-2.4.18-3/include/ " in RedHat7.3.
         FOR EXAMPLE, " INCLUDEPATH=-I /usr/src/linux-2.4.18-14/include/ " in RedHat8.0.

    (5)wlanup/wlandown
         simple script file to activate/shut_down wireless lan.





< Installation >
Please try to load linux_24x.o first by "insmod -f rtl8180_24x.o".
If it doesn't work, you are suggested to compile loadable driver module following the steps as:

	(0)Make sure the C-compile version. Run "gcc -v".
       If gcc version is 2.xx, use release driver RTL8180_24x_RH73.zip.
       If gcc version is 3.xx, use release driver RTL8180_24x_RH90.zip.

	(1)Modify macros in Makefile.
         KERNELRELEASE - represent kernel release version
         IO_FLAGS - pci I/O space mapping
         ENDIAN_FLAGS - big/little endian
         OP_MODE_FLAGS - Operation on either AP or Client mode
         DRV_FLAGS - Driver debugging messge ...etc.

    (2)Check pci module initialization and system call interfaces in the provided source code,
       r8180_pci_init.c ....etc.

	(3)Run 'make' to generate new driver module.

        (4)Run 'make install' to install new driver module.

	(5)Refer to < Set wireless lan MIBs > and modify script files, 
             wlanup/wlandown, to set Wireless LAN specific parameters.
             Run wlanup/wlandown to activate/shut_down wireless lan.
             Usage:
               ./wlanup {ap|infra|adhoc}
               ./wlandown
             Note:
               - "./wlanup ap" works if OP_MODE_FLAGS is assigned RTL_ACT_AS_AP in Makefile.
               - "./wlanup {infra|adhoc}" works if OP_MODE_FLAGS is assigned RTL_ACT_AS_AP
                 in Makefile.




< Set wireless lan MIBs >
This driver uses Wireless Extension as an interface allowing you to set
Wireless LAN specific parameters.
Current driver supports "iwpriv", manipulate driver private ioctls, to set MIBs.
