NAME
     mc - Ethernet driver for Am79C940 (MACE) on-board Ethernet

SYNOPSIS
     mc* at obio?

DESCRIPTION
     The mc interface provides access to a 10 Mb/s Ethernet network via the
     AMD Am79C940 (MACE) Ethernet chip set.

     Each of the host's network addresses is specified at boot time with an
     SIOCSIFADDR ioctl(2). The mc interface employs the address resolution
     protocol described in arp(4) to dynamically map between Internet and Eth-
     ernet addresses on the local network.

HARDWARE
     The mc interface supports the on-board Ethernet of the following ma-
     chines:

           Centris 660AV
           Quadra 660AV
           Quadra 840AV

DIAGNOSTICS
     mc0 at obio0: address %s.  This is a normal autoconfiguration message
     noting the 6 byte physical Ethernet address of the adapter.

SEE ALSO
     ae(4), arp(4), inet(4), netintro(4), sn(4), ifconfig(8)

HISTORY
     The mc interface first appeared in NetBSD 1.3.

AUTHORS
     The mc Ethernet driver was written by Dave Huang.
