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.
