10 Mb/s Ethernet interface

|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
interface provides access to a 10 Mb/s Ethernet network through a
|
|
.Tn DEC DELQA-YM
|
|
.Tn Q-bus
|
|
controller.
|
|
.Pp
|
|
Each of the host's network addresses
|
|
is specified at boot time with an
|
|
.Dv SIOCSIFADDR
|
|
.Xr ioctl 2 .
|
|
The
|
|
.Nm
|
|
interface employs the address resolution protocol described in
|
|
.Xr arp 4
|
|
to dynamically map between Internet and Ethernet addresses on the local
|
|
network.
|
|
.Sh DIAGNOSTICS
|
|
.Bl -diag
|
|
.It qt%d: chained packet.
|
|
A packet received from the network was longer than the allowed max length
|
|
and is therefore discarded.
|
|
This is usually because a host on the local network is behaving badly.
