Recently I try to build a network topology to test redirect_map, the topology is as below and the build script in the attachment(setup_env.sh).
My test case is run `ping` from netns ns1 to 192.168.2.2 in netns ns2. I load xdp prog to vhost1 and vhost2. What the prog do is just use redirect_map to redirect package from one ingress to another egress(AFAIK, redirect func is working for that, ifx me if I am wrong).
The result is I can't ping from one netns to another. The xdp prog is in the attachment(xdp_ping.py).
