QE(4) BSD/vax Kernel Interfaces Manual QE(4)NAMEqe — DEC DEQNA Q-bus 10 Mb/s Ethernet interface
device qe0 at uba? csr 174440 vector qeintr
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 set‐
ting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.
