Feel free to update the manpage. These features were probably left out because the designers thought it only suits packet monkeys perhaps? $ grep -n SOCK_RAW /usr/include/sys/socket.h 52:#define SOCK_RAW 3 /* raw-protocol interface */ $ > I would like to port a program for testing free space optics devices from > Linux to OpenBSD.

Perhaps you are confusing it with SOCK_PACKET which is linux only afaik and does not exist in BSD. To send layer 2 frames from userland your only option is bpf(4) injects and tun(4) writes when in layer 2 mode. > Should I investigate SOCK_RAW or is there a different mechanism under OpenBSD > how to send a raw Ethernet frame?
