IL(4)

NAME
il - Interlan NI1010 10 Mb/s Ethernet interface

SYNOPSIS
device il0 at uba0 csr 164000 vector ilrint ilcint

DESCRIPTION
The il interface provides access to a 10 Mb/s Ethernet network through an Interlan 1010 or 1010A controller.

Each of the host's network addresses is specified at boot time with an SIOCSIFADDR ioctl(2). The il interface employs the address resolution protocol described in arp(4) 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. The use of trailers is negotiated with ARP. This negotiation 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.

il%d: setaddr didn't work. The interface was unable to reprogram its physical ethernet address. This may happen with very early models of the interface. This facility is used only when the controller is not the first network interface configured for XNS. The oldest interface tested (2.7.1.0.1.45) has never failed in this way.

il%d: reset failed, csr=%b.

il%d: status failed, csr=%b.

il%d: hardware diag failed, csr=%b.

il%d: verifying setaddr, csr=%b.

il%d: stray xmit interrupt, csr=%b.

il%d: can't initialize. The above messages indicate a probable hardware error performing the indicated operation during autoconfiguration or initialization. The status field in the control and status register (the low-order four bits) should indicate the nature of the failure. See the hardware manual for details.
