SP-AL
1.7.4 Dual Gigabit Ethernet Ports
Two Gigabit Ethernet ports on the front panel support the Intel
i211AT (MAC/PHY) GbE controller (i210IT for extreme tempera-
ture operating support), which provides:

IEEE 802.3az Energy Efficient Ethernet

IEEE 1588/802.1AS precision time synchronization

IEEE 802.3av traffic shaper

Interrupt moderation, VLAN support, IP checksum offload

PCIe OBFF (Optimized Buffer Flush/Fill) for improved sys-
tem power management

Four transmit and four receive queues

RSS and MSI-X to lower CPU utilization in multi-core sys-
tems

ECC - error correcting memory in packet buffers

Wake-On-LAN

NC-SI for greater bandwidth passthrough

Preboot eXecution Environment (PXE) flash interface sup-
port

Jumbo frame support
