NAME

6       qe - DEC DEQNA Q-bus 10 Mb/s Ethernet interface

SYNOPSIS

DESCRIPTION

13       The  qe interface provides access to a 10 Mb/s Ethernet network through
14       the DEC DEQNA Q-bus controller.
15
16       Each of the host's network addresses is specified at boot time with  an
17       SIOCSIFADDR  ioctl.   The  qe  interface employs the address resolution
18       protocol described in arp(4P) to map dynamically  between Internet  and
19       Ethernet addresses on the local network.
20
21       The interface normally tries to use a ``trailer'' encapsulation to min‐
22       imize copying data on input and output.  The use of trailers is negoti‐
23       ated  with  ARP.   This negotiation may be disabled, on a per-interface
24       basis, by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl.
