2 ISCSI Boot Network proxy/ARP Offload support Security & Manageability Intel vPro support with appropriate Intel chipset componnets (82579LM SKU) MACSec support1 Performance Jumbo Frames (up to 9 kB)2 & Receive Side Scaling (RSS) Two Queues (Tx & Rx) Power Flexible power configuration: use either the PCH Vdc or iSVR. Reduced power consumption during normal operation and power down modes Integrated Intel Auto Connect Battery Saver (ACBS) Single-pin LAN Disable for easier BIOS implementation Fully integrated Switching Voltage Regulator (iSVR) Low Power LinkUp (LPLU) MAC/PHY Interconnect PCIe-based interface for active state operation (S0 state) SMBus-based interface for host and management traffic (Sx low power state)

3 Package/Design 48-pin package, 6 x 6 mm with a mm lead pitch and an Exposed Pad* for ground Three configurable LED outputs Integrated MDI interface termination resistors to reduce BOM costs Reduced BOM cost by sharing SPI flash with PCH1. MACSec is not compatible with Intel Active Management Technology2.
