Setup Snapgear on IXP425

1. Prepare for required resources:
  Fedora Linux 7

  arm-linux-tools-20061213.tar.gz
  snapgear-3.5.0.tar.gz
  BSD_ixp400AccessLibrary-2_4.zip
  IPL_ixp400NpeLibrary-2_4.zip
  snapgear-modules-20071004.sh
  sharutils-4.6.3-1.fc7.i386.rpm

2. Compile kernel

  2.1 Install Fedora Linux 7 with basic development tools (i.e. gcc)

  2.2 Unzip snapgear

      tar xzf snapgear-3.5.0.tar.gz

  2.3 Unzip arm-linux cross compiler to folder /opt
      tar xzf  arm-linux-tools-20061213.tar.gz -C /opt
  2.4 Make sure sharutil RPM is installed

      rpm -i sharutils-4.6.3-1.fc7.i386.rpm
  2.5 Patch snapgear 

      chmod 777 snapgear-modules-20071004.sh
      ./snapgear-modules-20071004.sh
      cd snapgear
      patch -p1 < ../snapgear-20071004.patch

  2.6 Unzip ixp400 driver
      mkdir -p modules/ixp425/ixp400-2.4
      cd modules/ixp425/ixp400-2.4
      unzip ../../../../BSD_ixp400AccessLibrary-2_4.zip
      unzip ../../../../IPL_ixp400NpeLibrary-2_4.zip
      patch -p1 < ../../../../modules-csr2.4-20071004.patch

  2.7 Configure and compile source code
      export PATH=/opt/usr/local/bin/:$PATH
      make CROSS_COMPILE=arm-linux- ARCH=arm menuconfig, then configure as follows:

make CROSS_COMPILE=arm-linux- ARCH=arm

3. Network Configuration
