4.1Intel® 82546EB Dual-Port Gigabit Ethernet Controller
The Intel® 82546EB Dual-Port Gigabit Ethernet Controller is a single PCI device with two full Gigabit Ethernet MAC and PHY layer functions. It provides two standard IEEE 802.3 Ethernet interfaces with 1000Base-T, 100Base-TX, and 10Base-T applications. The controller manages dual MAC and PHY functions and directly interfaces with the PCI-X primary bus.
