Power Management

Wake on LAN (Magic Packet, Wake Up Frame, specific pattern) is supported at 10/100 Mbps operation only.
NOTES:
Adapter speed connection when the system is down waiting for a wake-up signal is either 10 Mbps or 100 Mbps,
but can return to 1000 Mbps when the system is up and running if connected to a 1000 Mbps capable switch.
Systems intending to use Wake on LAN (WOL) should be connected to a switch capable of both 1000 and 10/100
Mbps speeds.
Dell supports Wake on LAN on one adapter in the system at a time.

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.
Dual DMA Channels
The PCI interface on Broadcom NetXtreme Gigabit Ethernet adapters contains two independent DMA channels for simultaneous
read and write operations.
32-Bit or 64-Bit PCI Bus Master
Compliant with PCI Local Bus Rev 2.3, the PCI interface on Broadcom NetXtreme Gigabit Ethernet adapters is compatible with
both 32-bit and 64-bit PCI buses. As a bus master, the adapter requests access to the PCI bus, instead of waiting to be
polled.
ASIC with Embedded RISC Processor
The core control for Broadcom NetXtreme Gigabit Ethernet 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.
Broadcom Advanced Control Suite 3
Broadcom Advanced Control Suite 3 (BACS 3), a component of the Broadcom teaming software, is an integrated utility that
provides useful information about each network adapter that is installed in your system. The BACS 3 utility also enables you
to perform detailed tests, diagnostics, and analyses on each adapter, as well as to modify property values and view traffic
statistics for each adapter. BACS 3 is used on Windows operating systems to configure teaming and to add VLANs. See
Broadcom Advanced Control Suite 3 for detailed information and instructions.
