ec
3Com 3c400 Multibus Ethernet interface driver

ec0 at mbmem0 addr 0xe0000 ipl 3
ec1 at mbmem0 addr 0xe2000 ipl 3

The ec interface provides access to the 10 Mb/s Ethernet network via the 3Com 3c400 Ethernet chip set.

Each of the host's network addresses is specified at boot time with an SIOCSIFADDR ioctl(2). The ec interface employs the Address Resolution Protocol described in arp(4) to dynamically map between Internet and Ethernet addresses on the local network.
