The intel product documents are confused about which chips they
use. The clearest split is something along the lines of:
7 82599EB -- PCI Express* (PCIe*) 2.0, dual port 10 Gigabit
Ethernet controller
7 82599ES -- Serial 10 GbE backplane interface for blade
implementations (includes the 82599EB SKU functionality plus serial).

There are mentions of 82598 10GbaseT working, I don't see why
82599 10GbaseT wouldn't work off hand.
