	Link layer selector length.
u_char	sdl_type
	Interface type.

Detailed Description

Structure of a Link-Level sockaddr.

Note

This is conditionally included, with the condition being that it hasn't already been defined elsewhere. This is normally part of sys/socket.h on older systems, but isn't always included on some newer systems, so it's provided here for completeness and to ensure a successful compilation.
