Hi Liz, I got the following error, could you help to figure out what was wrong?

root@iubuntu2004:~/ebpf-beginners# python3.9 packet.py bpf: Attaching prog to eth0: Operation not supportedTraceback (most recent call last): File "/root/ebpf-beginners/packet.py", line 32, in b.attach_xdp(dev="eth0", fn=b.load_func("hello_packet", File "/usr/lib/python3/dist-packages/bcc/init.py", line 726, in attach_xdp raise Exception("Failed to attach BPF to device %s: %s" Exception: Failed to attach BPF to device b'eth0': Success

Hi @peiqiaoWang @wangsu502, just change eth0 with your actual network interface, for example: ens3.
