This part is the tricky part for supporting ECN. If the underlying socket is a UDPConn,
ReadMsgUDP(buf, oob)is used which returns out of band data like ToS. It works fine for now, but I honestly haven't thought about the cases where theconnis not a pure socket, but a class that implementsnet.PacketConn(like a Proxy or a Wrapper), and in this case we don't want to bypass the Wrapper's methods. However, for now, I think this is fine.
