qeDEC DEQNA Q-bus Ethernet device

qe0 at uba? csr 0174440

The qe interface provides access to a 10 Mb/s Ethernet network through the DEC DEQNA Q-bus controller.

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(2).
