Such drivers must request the ether attribute in their files declaration andcall the appropriate functions as specified below.FDDI drivers must request the "fddi" attribute in their "files" declaration and call the functions tagged with"fddi_" or "FDDI_" instead, where different. Some macros are shared.Note that you also need the arp(9) stuff tosupport IPv4 on your hardware.ether_ifattach()Perform the device-independent, but Ethernet-specific initialization of the interface pointed to byifp.Among other duties, this function creates a record for the link level address in the interface’saddress list and records the link level address pointed to by lla there.Youmust call this function from the driver’s attach function.fddi_ifattach()corresponding function for FDDI devices.NetBSD 3.0 March 3, 1997 1
