•
Dual interconnect between the Integrated LAN Controller and the Physical Layer
•
(PHY):
 PCI Express-based interface for active state operation (S0) state
 SMBUS for host and management traffic (Sx low power state)
Compliant to IEEE 802.3x flow control support
•
802.1p and 802.1q
•
TCP, IP, and UDP checksum offload (for IPv4 and IPv6)
•
• Full device driver compatibility
In addition, the Intel 82579LM Gigabit Ethernet Controller supports Intel AMT, which is
a part of Intel's vPro™ technology. The associated RJ-45 LAN connector has been
