# Instructions to how to run this program
# 1. Install PythonBPF: pip install pythonbpf
# 2. Run the program: python examples/xdp_pass.py
# 3. Run the program with sudo: sudo tools/check.sh run examples/xdp_pass.o
# 4. Attach object file to any network device with something like ./check.sh xdp examples/xdp_pass.o tailscale0
# 5. send traffic through the device and observe effects
