.Sh NAME
.Nm qt

.Tn DEC DELQA-PLUS (DELQA-YM)
.Tn Q-bus
10 Mb/s Ethernet interface
.Sh SYNOPSIS
.Cd "qt0 at uba? csr 174440"
.Cd "qt1 at uba? csr 174460"
.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.
.El
.Sh SEE ALSO
.Xr arp 4 ,
.Xr inet 4 ,
.Xr netintro 4
.Sh HISTORY
The
.Nm
driver first appeared in
.Bx 2.11 .
It was later ported to
.Nx 2.0 .
