82575EB Datasheet, PDF (9/62 Pages) Intel Corporation – Intel® 82575EB Gigabit Ethernet Controller Datasheet

Manageability Features — Intel^® 82575EB Gigabit Ethernet Controller
Features
Advanced packet filtering
IEEE 802.1q VLAN support with VLAN tag insertion, stripping
and packet filtering for up to 4096 VLAN tags
Double Vlan
Descriptor ring management hardware for transmit and receive
9.5 kByte jumbo frame support
Receive Side Scaling (RSS)
VMDq
Direct Cache Access (DCA)
Fragmented UDP checksum offload for packet reassembly
Benefits
• 16 exact matched packets (unicast or multicast)
• 4096-bit hash filter for multicast frames
• Promiscuous (unicast and multicast) transfer mode support
• Optional filtering of invalid frames
• Ability to create multiple virtual LAN segments
• Insert in Tx and extract in Rx
• Optimized fetching and write-back mechanisms for efficient
system memory and PCI bandwidth usage
• High throughput for large data transfers on networks
supporting jumbo frames
• Multiple Rx queues
• Virtualization environment. In this environment, packets
dedicated to different virtual machines can be routed to
different queues, thus easing the routing of these packets
to the target machine.
• The IO device activates a pre-fetch engine in the CPU that
loads the data into the CPU cache ahead of time, before
use, eliminating cache misses and reducing CPU load.
