qn —
Ethernet driver for Fujitsu MB86950 based boards
The qn interface provides access to the 10 Mb/s Ethernet
  network via the Fujitsu MB86950 Ethernet chip set.
Each of the host's network addresses is specified at boot time
    with an SIOCSIFADDR
    ioctl(2). The
    qn interface employs the address resolution protocol
    described in arp(4) to
    dynamically map between Internet and Ethernet addresses on the local
    network.
The qn interface supports the following Zorro II
  expansion cards:
  - QuickNet
- Resource Management Force's Ethernet card, manufacturer 2011,
      product 2
 
Multicasting not done yet. If the driver happens to lock up, you may use
  ifconfig(8) to force the
  driver down and up again. This usually helps.
The qn interface first appeared in
  NetBSD 1.1
