ed —
Ethernet driver for DP8390-based Ethernet boards
The ed interface provides access to a 10 Mb/s Ethernet
  network via the DP8390 Ethernet chip set.
Each of the host's network addresses is specified at boot time
    with an SIOCSIFADDR
    ioctl(2). The
    ed interface employs the address resolution protocol
    described in arp(4) to
    dynamically map between Internet and Ethernet addresses on the local
    network.
The ed interface supports the following Zorro II
  expansion cards:
  - AMIGANET
- Hydra Systems' Ethernet card, manufacturer 2121,
    product 1
- LAN ROVER
- ASDG's Ethernet card, manufacturer 1023, product 254
 
The ed interface first appeared in
  NetBSD 1.0. It was rewritten by Frank Wille for
  NetBSD 6.1.
