.Sh NAME
|
|
.Nm ex
|
|
.Nd Excelan 10 Mb/s Ethernet interface
|
|
.Sh SYNOPSIS
|
|
.Cd "device ex0 at uba0 csr 164000 vector excdint"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm ex
|
|
interface provides access to a 10 Mb/s Ethernet network through
|
|
an Excelan controller used as a link-layer interface.
|
|
.Pp
|
|
Each of the host's network addresses
|
|
is specified at boot time with an
|
|
.Dv SIOCSIFADDR
|
|
.Xr ioctl 2 .
|
|
The
|
|
.Nm ex
|
|
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
|
|
.Dq 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 "ex%d: HW %c.%c, NX %c.%c, hardware address %s."
|
|
This provides firmware revisions levels, and is expected during
|
|
autoconfiguration.
|
|
.Pp
|
|
.It ex%d: can't initialize.
|
|
There was a failure in allocating unibus resources for the device.
|
|
.Pp
|
|
.It "ex%d: configuration failed; cc = %x."
|
|
The hardware indicated an error when trying to initalize itself.
|
|
The error code returned is described at length in the device
|
|
Reference Manual.
|
|
.Pp
|
|
.It ex%d: receive error %b.
|
|
The hardware indicated an error
|
|
in reading a packet from the cable.
|
|
Specific Error bits are provided
|
|
.Pp
|
|
.It ex%d: transmit error %b.
|
|
The hardware indicated an error
|
|
in transmitting a packet to the cable or an illegally sized packet.
|
|
Specific Error bits are provided
|
|
.Pp
|
|
.It ex%d: can't handle af%d.
|
|
The interface was handed
|
|
a message with addresses formatted in an unsuitable address
|
|
family; the packet was dropped.
