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.
