SN(4)

NAME
sn - Ethernet driver for SONIC-based Ethernet adapters

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

In addition, the sn interface supports on-board Ethernet for 500-series PowerBooks and non-AV Quadras.

DIAGNOSTICS
sn%d at %s%d: address %s, type %s %dKB memory. This is a normal autoconfiguration message noting the 6 byte physical Ethernet address of the adapter, its manufacturer, and how much buffer memory it has.

HISTORY
The sn interface first appeared in NetBSD 1.3.
