+.Sh NAME
+.Nm sn
+.Nd National Semiconductor DP83932 (SONIC) based Ethernet device driver
+.Sh SYNOPSIS
+.Ss arc
+.Cd "sn0 at jazzio?"
+.Ss mac68k
+.Cd "sn* at obio?"
+.Cd "sn* at nubus?"
+.Sh DESCRIPTION
+The
+.Nm
+interface provides access to a 10 Mb/s Ethernet network via the
+National Semiconductor DP83932
+.Pq Tn SONIC
+Ethernet chip set.
+.Pp
+Each of the host's network addresses is specified at boot time with an
+.Dv SIOCSIFADDR
+.Xr ioctl 2 .
+The
+.Nm
+interface employs the address resolution protocol described in
+.Xr arp 4
+to dynamically map between Internet and Ethernet addresses on the
+local network.
+.Sh HARDWARE
+.Ss arc
+The
+.Nm
+driver supports on-board JAZZ based SONIC interfaces found
+on Acer PICA and NEC machines.
+.Ss mac68k
+The
+.Nm
+driver is currently known to support the following NuBus cards:
+.Bl -bullet -offset indent -compact
+.It
+Apple LC Twisted-pair (part #820-0532-A) PDS card
+.It
+Cayman Gatorcard PDS
+.It
+Dayna DaynaPort/E30
+.El
+.Pp
+In addition, the
+.Nm
+interface supports the following interfaces:
+.Bl -bullet -offset indent -compact
+.It
+on-board Ethernet for non-AV Quadras
+.It
+on-board Ethernet for 500-series PowerBooks
+.It
+Apple CS Ethernet Twisted-pair card for Comm Slot found on
+LC575, Quadra 630, LC630, and Performa 580.
+.El
+.Sh DIAGNOSTICS
+.Bl -diag -compact
+.It sn%d: transmit FIFO underrun
+.It sn%d: receive FIFO overrun
+.It sn%d: receive buffer exceeded
+.It sn%d: receive buffers exhausted
+.It sn%d: receive descriptors exhausted
+These messages indicate that the interface gets errors
+(due to heavy load etc.) and reinitialized.

+.Xr ifconfig 8
+.Sh HISTORY
+The
+.Nm
+interface for mac68k, which was derived from a driver for old
+.Nx Ns /pica
+port, first appeared in
+.Nx 1.3 .
+.Pp
+Jason Thorpe has rewritten a new machine independent SONIC driver which uses
+.Xr bus_dma 9
+and
+.Xr bus_space 9
+APIs after
+.Nx 1.5
+release, and
+.Nx Ns /arc
+has been switched to using the machine independent (MI) driver.
+.Pp
+.Nx Ns /mac68k
+has also been switched to using the MI driver after the
+.Nx 4.0
+release.
