Chapter 1: Introducing the AT-2973SX, AT-2973T, AT-2973T/4, and AT-VNC10S Adapters

Wake on LAN
(WOL) Feature
The WOL feature sets the speed at which the network adapter connects to
the network while the adapter is in Wake on LAN (WOL) mode which is
enabled automatically. The default speed for WOL mode is 100 Mb. An
adapter can negotiate speeds between 10 Mb and 100 Mb. You cannot
configure this feature because it is enabled automatically.
Note
The WOL feature is supported on the AT-2973T and AT-2973T/4
adapters. It is not supported on the AT-2973SX and AT-VNC10S
adapters. For more information, see “Limitations” on page 66.
Note
For specific systems, see your system documentation for
information about support of the WOL feature.
Adaptive
Interrupt
Frequency
The adapter driver intelligently adjusts host interrupt frequency based on
traffic conditions to increase overall application throughput. When traffic is
light, the adapter driver interrupts the host for each received packet,
minimizing latency. When traffic is heavy, the adapter issues one host
interrupt for multiple, back-to-back incoming packets, preserving host CPU
cycles.
ASIC with
Embedded RISC
Processor
The core control for Broadcom NetXtreme II adapters resides in a tightly
integrated, high-performance ASIC. The ASIC includes a RISC processor.
This functionality provides the flexibility to add new features to the card
and adapts it to future network requirements through software downloads.
This functionality also enables the adapter drivers to exploit the built-in
host offload functions on the adapter as host operating systems are
enhanced to take advantage of these functions.
