This is the package for pgtool of Realtek. There are two methods to use
this tool. The method 1 is through a script file. However, you have to use
the Method 2 if the Method 1 doesn't work.
If you use the embedded system, you maybe have to build "pgdrv.ko" first
for the target platform. Please reference the Step 2 of Method 2. And the
steps may be different.

Method 1:
Step 1: Run the script file to load the necessary elements.
# ./pgload.sh

Step 2: Run the pgtool "rtnicpg". Use /h to show user guide.
# ./rtnicpg /h | more

Step 3: Choose the cmd to pg.
Example: Read the EEPROM for the first NIC card.
# ./rtnicpg /r /eeprom /# 1

Step 4: Unload the elements of pgtool.
# rmmod pgdrv


Method 2:
Step 1: Unload all the NIC driver for Realtek.
# rmmod r8169
# rmmod r8168
# rmmod r8101

Step 2: Build the pgdrv.ko and install it.
# make clean all
# insmod pgdrv.ko

Step 3: Run the pgtool "rtnicpg". Use /h to show user guide.
# ./rtnicpg /h | more

Step 4: Choose the cmd to pg.
Example: Read the EEPROM for the first NIC card.
# ./rtnicpg /r /eeprom /# 1

Step 5: Remove the pgdrv.
# rmmod pgdrv

[NOTICE]
1. The applications are only for little-endian platform.
2. Must login with "root".
3. The NIC driver must be unload first or the pgdrv.ko cannot work.
