Thanks a lot!

Note that there are a few other places in bpftool where the attach point
should be added, would you mind updating them too? That would be: the
documentation page for bpftool-cgroup, the one for bpftool-prog, the
help message in prog.c, and the bash completion. It should all be
straightforward. You can try something like "grep recvmsg4
tools/bpf/bpftool" to find the relevant locations.

Best regards,
