For the receive section I think I have to change something in ndisc_recv_ns(), I'll figure that out. Maybe I need some (small) support from you, but I think we can do that off list.

If you change the "hardware address length", you can get
notification when you have new neighbor.
Even if you did not change that, you could introduce new
netevent notification.

I don't think we will see encrypted ND messages, but
IP layer should handle encrypted NDISC messages.
