I am not sure of the current status, but last time I have checked (FreeBSD 5.3 times), IIRC, there was some experimental driver for that chip. But now the latest I can see is a binary-only FreeBSD 5.4 driver from Marvell's site, after agreeing to some license: http://www.marvell.com/drivers/driverDisplay.do?dId=131&pId=34 I wondered why Intel did not put two PRO/1000 interfaces but has chosen to put a Yukon as the second interface. It was suggested to me that Intel believed the Yukon to be able to provide better throughput as it is connected to the PCI-Express bus - however Intel have their own (also called PRO/1000, so I'd assume some similarity, but can never be sure) Gigabit Ethernet chips for PCI-Express, so I do not understand this.
