NAME
qe
- DEC DEQNA
Q-bus
10 Mb/s Ethernet interface
SYNOPSIS
device qe0 at uba? csr 174440 vector qeintr
DESCRIPTION
The
qe
interface provides access to a 10 Mb/s Ethernet network through
the
DEC DEQNA
Q-bus
controller.
Each of the host's network addresses
is specified at boot time with an
SIOCSIFADDR
ioctl(2).
The
qe
interface employs the address resolution protocol described in
arp(4)
to map dynamically between Internet and Ethernet addresses on the local
network.
The interface normally tries to use a
``trailer''
encapsulation
to minimize copying data on input and output.
The use of trailers is negotiated with
ARP
This negotiation may be disabled, on a per-interface basis,
by setting the
IFF_NOTRAILERS
flag with an
SIOCSIFFLAGS
ioctl.
