sn
— National
Semiconductor DP83932 (SONIC) based Ethernet device driver
sn0 at jazzio?
sn* at obio?
sn* at nubus?
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.
The sn
driver supports on-board JAZZ based
SONIC interfaces found on Acer PICA and NEC machines.
The sn
driver is currently known to
support the following NuBus cards:
In addition, the sn
interface supports the
following interfaces:
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.
