Developing New Socket Option on 4.10

Hello, all, I am writing for help on my freebsd kernel hacking. I am working on 4.10, and intend to introduct a new socket option (say, SO_TAG_PAK) for my own kernel. When sending out a packet, if this option is set, the socket layer will produce a 20-byte tag, and finally this tag will be prepe
