Ah, I forgot about the "we'll just use IP protocol numbers as socket
option levels" behaviour (BSD-derived?). My Linux man page only talks
about SOL_TCP, but I have run into this before and should have
remembered.. my bad.
per my linux/socket.h:
> /* Setsockoptions(2) level. Thanks to BSD these must match IPPROTO_xxx */

(I won't get into why using wire-level-protocol constants for syscall
option numbering is a bad idea.. :)
