AFAICT, winsock's SOCK_RAW isn't what I need.
It lets you imipliment protocols on top of IP -- at least
that's what the documentation implies, and that's what's being
done by all the example code I can find.
I don't want to build on top of IP. I want to build an
arbitrary protocol on top of Ethernet, specifying the Ethernet
protocol number which I want to send/receive.
