The i82576 chip also has timestamp support, although I was told recently it's not as good as the 82580.
The I340 cards are based on the 82580, and yes, the timestamp support has been improved. The datasheet (an all-in-one programming guide as well now) should be available on http://www.intel.com/go/ethernet. Look for the one for the actual Ethernet controller (the 82580). Make sure you look at the Specification Update as well. I was looking into updating the driver for several parts, but NetBSD uses an older style of driver (unlike FreeBSD and Linux ) and it's pretty opaque to me. -- Hisashi T Fujinaka - htodd%twofifty.com@localhost BSEE(6/86) + BSChem(3/95) + BAEnglish(8/95) + MSCS(8/03) + $2.50 = latte
