Manual testing:

1. Run test/setup.sh to create a test network namespace and veth interface pair.
2. Load the AES-XDP program: sudo build/aes/xdp-loader build/aes/xdp_aes.o veth0
3. Start receiver: test/receiver.py 10.1.0.1 6500
4. Send packets: sudo ip netns exec xdp_test test/sender.py 10.1.0.1 6500
5. Capture packets with tcpdump: sudo tcpdump -nn -vv -i veth0
6. When done, delete the network namespace with sudo ip netns delete xdp_test.
