Haswell NICs - Intel i217LM and i210AT

[hotzen]

Hey,

I'm just browsing around on supermicro checking their new haswell UP-xeon lineup
( http://www.supermicro.com/products/motherboard/Xeon3000/#1150 ) and wonder what the difference between the following features is:

- Dual Gigabit Ethernet LAN ports (1x Intel® i217LM & 1x Intel® i210AT)
vs.
- Dual Gigabit Ethernet LAN ports via 2x Intel® i210AT

Can anyone explain the key difference?

Thanks alot

* 82574L: an independent, complete gigabit Ethernet controller.
* 82579LM: an gigabit Ethernet PHY which requires a controller (usually from the chipset) support.

From 1155 based MoBos.

Wild guess: AT = independent
