netdock —
Ethernet driver for Asante NetDock and Newer Ether
  MicroDock
The netdock interface provides access to a 10 Mb/s
  Ethernet network via the Asante NetDock and Newer Ether MicroDock, for
  PowerBook Duo series.
Each of the host's network addresses is specified at boot time
    with an SIOCSIFADDR
    ioctl(2). The
    netdock interface employs the address resolution
    protocol described in arp(4)
    to dynamically map between Internet and Ethernet addresses on the local
    network.
The netdock interface is currently known to support the
  following interfaces for PowerBook Duo series:
  - Asante NetDock
- Newer Ether MicroDock
 
  - netdock%d at nubus%d: address %s, type %s %dKB memory.
- This is a normal autoconfiguration message noting the 6 byte physical
      Ethernet address of the adapter, its manufacturer, and how much buffer
      memory it has.
Thenetdock interface first appeared in
  NetBSD 2.0.
