NAME

il − Interlan 10 Mb/s Ethernet controller

SYNOPSIS

IL0 at address 0x3fe820/017764040 vector 0x50/0120

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.
