NAME

     mc -- Ethernet driver for Am79C940 (MACE) onboard 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.

HARDWARE

     The mc interface supports the on-board Ethernet of the following mac68k machines:
	   -   Centris 660AV
	   -   Quadra 660AV
	   -   Quadra 840AV

     The mc interface supports the on-board Ethernet of the following macppc machines:
	   -   Apple Network Server (500 and 700)
	   -   Apple Power Macintosh (7300, 7500, 7600, 8500, 8600, 9500, and 9600)
	   -   Power Computing (PowerCenter, PowerCenter Pro, PowerCurve, PowerTower, PowerTower Pro, and PowerWave)

DIAGNOSTICS

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

HISTORY

     The mc interface first appeared in NetBSD 1.3.

AUTHORS

     The mc Ethernet driver was written by Dave Huang <khym@bga.com>.  The man page was written by Thomas Klausner <wiz@NetBSD.org> and Michael

NAME

     sn -- National Semiconductor DP83932 (SONIC) based Ethernet device driver

SYNOPSIS

   arc
     sn0 at jazzio?

   mac68k
     sn* at obio?
     sn* at nubus?

DESCRIPTION

     The sn interface provides access to a 10 Mb/s Ethernet network via the National Semiconductor DP83932 (SONIC) Ethernet chip set.

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

HARDWARE

   arc
     The sn driver supports on-board JAZZ based SONIC interfaces found on Acer PICA and NEC machines.

   mac68k
     The sn driver is currently known to support the following NuBus cards:
	   o   Apple LC Twisted-pair (part #820-0532-A) PDS card
	   o   Cayman Gatorcard PDS
	   o   Dayna DaynaPort/E30

     In addition, the sn interface supports the following interfaces:
	   o   on-board Ethernet for non-AV Quadras
	   o   on-board Ethernet for 500-series PowerBooks
	   o   Apple CS Ethernet Twisted-pair card for Comm Slot found on LC575, Quadra 630, LC630, and Performa 580.

DIAGNOSTICS

     sn%d: transmit FIFO underrun
     sn%d: receive FIFO overrun
     sn%d: receive buffer exceeded
     sn%d: receive buffers exhausted
     sn%d: receive descriptors exhausted  These messages indicate that the interface gets errors (due to heavy load etc.) and reinitialized.

SEE ALSO

     arp(4), inet(4), netintro(4), ifconfig(8)

HISTORY

     The sn interface for mac68k, which was derived from a driver for old NetBSD/pica port, first appeared in NetBSD 1.3.

     Jason Thorpe has rewritten a new machine independent SONIC driver which uses bus_dma(9) and bus_space(9) APIs after NetBSD 1.5 release, and
     NetBSD/arc has been switched to using the machine independent (MI) driver.

     NetBSD/mac68k has also been switched to using the MI driver after the NetBSD 4.0 release.
