### NAME

ec - 3Com 3c400 Multibus Ethernet interface driver

### SYNOPSIS

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

### DESCRIPTION

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.
