IL 4 "27 July 1983"
C 5 NAME
il - Interlan 10 Mb/s Ethernet interface
SYNOPSIS
"device il0 at uba0 csr 161000 vector ilrint ilcint" DESCRIPTION
The
il interface provides access to a 10 Mb/s Ethernet network through
an Interlan controller.
The host's Internet address is specified at boot time with an SIOCSIFADDR ioctl. The il interface employs the address resolution protocol described in arp (4P) to dynamically map between Internet and Ethernet addresses on the local network.
The interface normally tries to use a ``trailer'' encapsulation to minimize copying data on input and output. This may be disabled, on a per-interface basis, by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.
DIAGNOSTICS
il%d: input error. The hardware indicated an error
in reading a packet off the cable or an illegally sized packet.
il%d: can't handle af%d. The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped.

BUGS
The PUP protocol family should be added.
