Manageability Features

Advanced packet filtering

• 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

IEEE 802.1q VLAN support with VLAN tag insertion, stripping

and packet filtering for up to 4096 VLAN tags

• Ability to create multiple virtual LAN segments

Double Vlan

• Insert in Tx and extract in Rx

Descriptor ring management hardware for transmit and receive

• Optimized fetching and write-back mechanisms for efficient

system memory and PCI bandwidth usage

9.5 kByte jumbo frame support

• High throughput for large data transfers on networks

supporting jumbo frames

Receive Side Scaling (RSS)

• Multiple Rx queues

VMDq

• 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.

Direct Cache Access (DCA)

• 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.

Fragmented UDP checksum offload for packet reassembly
