RTL8192SU Linux driver
   --This driver supports RealTek rtl8192SU USB Wireless LAN NIC
     for
     2.6 kernel:
     Fedora Core 2/3/4/5, Debian 3.1, Mandrake 10.2/Mandriva 2006, 
     SUSE 9.3/10.1/10.2, Gentoo 3.1, Ubuntu 7.10/8.04, etc.
     2.4 kernel:
     Redhat 9.0/9.1
===============================================================================
            Component 
===============================================================================
The driver is composed of several parts:
   1. Firmare to make nic work
           1.1 firmare/RTL8192SU
   2. Module source code
      2.1 ieee80211 
      2.2 HAL/rtl8192u
      2.3 wpa_supplicant-0.5.10 (User can download the latest version from 
          internet also, but it is suggested to use default package contained
          in the distribution because there should less compilation issue.)
   
   3. Script to build the modules
      3.1 Makefile 
   4. Script to load/unload modules
      4.1 wlan0up 
      4.2 wlan0down 
   5. Script and configuration for DHCP
       5.1 wlan0dhcp
      5.2 ifcfg-wlan0
   6. Example of supplicant configuration file:
      6.1 wpa1.conf
   7. Script to run wpa_supplicant
      7.1 runwpa
===============================================================================
            Installation 
===============================================================================
<<Method 1>>
Runing the scripts accomplish all operations including building up modules 
from the source code, installing driver to the kernel and starting up the nic.
   1. Build up the drivers from the source code
     make
   2. Install the driver to the kernel
          make install
          reboot
   3. bring up wlan if nic is not brought up by GUI, such as NetworkManager
     ifconfig wlan0 up 
     Note: use ifconfig to check whether wlan0 is brought up and use iwconfig to check your wlan interface name, 
                since it may change wlan0 to wlan1,etc.
<<Method 2>>
Or only load the driver module to kernel and start up nic.
    1. Build up the drivers from the source code
     make
         2. Copy firmware to /lib/firmware/ or /lib/firmware/(KERNEL_VERSION)/
            cp -rf firmware/RTL8192SU /lib/firmware
          or
            cp -rf firmware/RTL8192SU /lib/firmware/(KERNEL_VERSION)
          Note: This depends on whether (KERNEL_VERSION) subdirectory exists under /lib/firmware
    3. Load driver module to kernel and start up nic.
     ./wlan0up
          Note: when "insmod: error inserting 'xxxx.ko': -1 File exists" comes out
                after run ./wlan0up, please run ./wlan0down first, then it should 
                be ok..
     Note: If you see the message of "unkown symbol" during ./wlan0up, it
      is suggested to build driver by <<Method 1>>.
