One weird thing about all of this is that sockaddr_dl is used at the

it's an IP interface concept. It's odd that the range of IP interface index
not that weird: sockaddr_dl is a socket address of type (sa_type
and/or sdl_type) AF_LINK. That concept (as well as that of an interface
index) is more general across diverse OS'es than "datalink_id_t".
Yes, you're making my point. Solaris has no such general concept that
cuts across the layers of the stack, and so picking one that solely
exists at the IP layer isn't architecturally sane. For example, you can
operate on a link that isn't plumbed by IP using sockaddr_dl...
