|
.Sh SYNOPSIS
|
|
|
|
|
.Cd "device il0 at uba0 csr 164000 vector ilrint ilcint"
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm il
|
|
|
|
|
interface provides access to a 10 Mb/s Ethernet network through
|
|
|
|
|
an Interlan 1010 or 1010A controller.
|
|
|
|
|
.Pp
|
|
|
|
|
Each of the host's network addresses
|
|
|
|
|
is specified at boot time with an
|
|
|
|
|
.Dv SIOCSIFADDR
|
|
|
|
|
.Xr ioctl 2 .
|
|
|
|
|
The
|
|
|
|
|
.Nm il
|
|
|
|
|
interface employs the address resolution protocol described in
|
|
|
|
|
.Xr arp 4
|
|
|
|
|
to dynamically map between Internet and Ethernet addresses on the local
|
|
|
|
|
network.
|
|
|
|
|
.Pp
|
|
|
|
|
The interface normally tries to use a ``trailer'' encapsulation
|
|
|
|
|
to minimize copying data on input and output.
|
|
|
|
|
The use of trailers is negotiated with
|
|
|
|
|
.Tn ARP .
|
|
|
|
|
This negotiation may be disabled, on a per-interface basis,
|
|
|
|
|
by setting the
|
|
|
|
|
.Dv IFF_NOTRAILERS
|
|
|
|
|
flag with an
|
|
|
|
|
.Dv SIOCSIFFLAGS
|
|
|
|
|
.Xr ioctl .
|
|
|
|
|
.Sh DIAGNOSTICS
|
|
|
|
|
.Bl -diag
|
|
|
|
|
.It il%d: input error.
|
|
|
|
|
The hardware indicated an error
|
|
|
|
|
in reading a packet off the cable or an illegally sized packet.
|
|
|
|
|
.Pp
|
|
|
|
|
.It 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.
|
|
|
|
|
.Pp
|
|
|
|
|
.It 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
|
|
|
|
|
.Tn XNS .
|
|
|
|
|
The oldest interface tested (2.7.1.0.1.45) has never failed in this way.
|
|
|
|
|
.Pp
|
|
|
|
|
.It il%d: reset failed, csr=%b.
|
|
|
|
|
.It il%d: status failed, csr=%b.
|
|
|
|
|
.It il%d: hardware diag failed, csr=%b.
|
|
|
|
|
.It il%d: verifying setaddr, csr=%b.
|
|
|
|
|
.It il%d: stray xmit interrupt, csr=%b.
|
|
|
|
|
.It 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.
