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.   The  qe  interface employs the address resolution
       protocol described in arp(4P) to map dynamically  between Internet  and
       Ethernet addresses on the local network.

       The interface normally tries to use a ‘‘trailer’’ encapsulation to min‐
       imize copying data on input and output.  The use of trailers is negoti‐
       ated  with  ARP.   This negotiation may be disabled, on a per-interface
       basis, by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.
