qe - DEC DEQNA Q-bus 10 Mb/s Ethernet interface
NQE qe_controllers # DEQNA
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 minimize copying data on input and output. The use of trailers is nego-
tiated with ARP. This negotiation may be disabled, on a per-interface basis, by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS
