概述

Description

The BCM57781B0KMLG is a Broadcom NetXtreme PCIe Ethernet controller used in servers and high-end workstations to provide network connectivity. B0 is the silicon revision; KMLG is the packaging/leadframe code.
Key capabilities (typical): PCIe-based NIC with high-throughput Ethernet (1 GbE to 10 GbE variants depending on the card), hardware offloads (TCP/IP offload, checksum, LSO/LRO), multi-queue RSS for multi-core performance, VLAN offloads, and virtualization support (SR-IOV/VMDq).
Drivers and support: Broadcom provides Windows and Linux drivers; NICs based on this controller are common in OEM server cards.
For exact specifications (speed, PCIe lanes, memory/ROM details, and feature flags), consult the official BCM57781 datasheet/product brief from Broadcom or the card’s vendor.

Features

I don’t have the exact datasheet for BCM57781B0KMLG. Here are the typical features of Broadcom NetXtreme II 57xxx 10GbE NICs (SKU dependent):
- PCIe host interface (Gen2 x4)
- Integrated MAC + PHY (dual-port or quad-port variants by SKU)
- 10GbE Ethernet support (10GBASE-T copper; fiber options may exist in other SKUs)
- Jumbo frames support (up to ~9K)
- Hardware offloads: TCP/IP offload, LSO/LRO, checksum offload
- Networking features: RSS for multi-core throughput, VMQ/VMDq virtualization support, VLAN, QoS
- Link aggregation (LACP), fault-tolerant bonding
- Power management and thermal monitoring
- BroadOS/Linux/Windows driver support (widely used in servers/workstations)
For precise specs (port count, exact PHY options, supported speeds, and feature set for B0KMLG), please share the datasheet link or confirm the exact SKU details.
