### NAME

qt - DEC DELQA-PLUS (DELQA-YM) Q-bus 10 Mb/s Ethernet interface

### SYNOPSIS

qt0 at uba? csr 174440 qt1 at uba? csr 174460

### DESCRIPTION

The qt interface provides access to a 10 Mb/s Ethernet network through a DEC DELQA-YM Q-bus controller.

Each of the host's network addresses is specified at boot time with an ```SIOCSIFADDR` ioctl(2). The qt interface employs the address resolution protocol described in arp(4) to dynamically map between Internet and Ethernet addresses on the local network.

### DIAGNOSTICS

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.

### SEE ALSO

arp(4), inet(4), netintro(4)

### HISTORY

The qt driver first appeared in 2.11BSD. It was later ported to NetBSD2.0.
