Our ping API is simple, but it's also very limited:
Rust code
pub fn ping(dest: ipv4::Addr) -> Result<(), String> // called as: ping(ipv4::Addr([8, 8, 8, 8])).unwrap();
It doesn't allow specifying the TTL (time to live) of packets, it doesn't allow specifying the timeout, it doesn't let one specify the data to send along, and it doesn't give us any kind of information on the reply.
