We are porting the FreeBSD SysKonnect gigabit ethernet driver to NetBSD.
<http://www.posi.net/freebsd/drivers/driver-info.phtml?ID=18>
At present we don't have their dual-port card, but we will be
getting one. The SysKonnect has a single DMA engine on the card and
a pair of Xaqti MACs on it.
I believe the correct behaviour would be us to create an attachment for the
DMA device, create a logical bus behind it, and then attach two devices
behind that. Are there simpler ways? The FreeBSD driver appears to cheat.
