DESCRIPTION
The sw is the Sun 4/100 on-board SCSI controller based on the NCR 5380
chip, found only on Sun 4/100 workstations. The sw driver is actually
implemented as part of the si(4) driver.
DEVICE FLAGS
0x01 Use DMA (polled)
0x02 Use DMA completion interrupts
0x04 Allow disconnect/reconnect
The sw device flags may be OR'd together to enable any combination of the
features listed above. If no flags are specified, the device will use
polled DMA by default.

The sw driver first appeared in NetBSD.
BUGS
The sw driver only supports polled DMA at this time.
