These are the links that showing that k8 can delegates caps.
Are you saying that you know of folks who specifically
delegate cap_sys_admin and cap_net_admin _only_ to a container to run bpf in there?

Yes, we need cap_sys_admin only to load bpf:
tc filter add dev eth0 ingress matchall action bpf obj ./tc_test_kern.o sec test

I'm not sure to understand why cap_net_admin is not enough to run the previous
command (ie why load is forbidden).

I want to avoid sys_admin, thus cap_bpf will be ok. But we need to manage the
backward compatibility.
