```bash

make 

bash install_frdev.sh

ls -hl /dev/frdev*

gcc fripadm_black_in_exe.c -o fripadm_black_in_exe

gcc fripadm_white_in_exe.c -o fripadm_white_in_exe

ping 192.168.31.100 

bash fripadm_black_in.sh insert '192.168.31.100 8.8.8.8 1.100-1.*.1'

bash fripadm_black_in.sh switch

bash fripadm_black_in.sh dump

# Notes:

The little patch below will solve the compiling problem in `3.10.0-327.el7.x86_64` (because of the recently kernel updates).
