Intel
®
82579LM Gigabit Ethernet Controller and
Intel
®
82574L Gigabit Ethernet Controller
The ethernet controllers support the following features:
•
10/100/1000 BASE-T IEEE 802.3 compliant
•
Energy Efficient Ethernet (EEE) IEEE802.3az support (Low Power Idle [LPI] mode)
•
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
colored red for easy identification.
