概要
Description
BCM57781B0KMLG is a Broadcom NetXtreme II 10-Gigabit Ethernet Network Interface Controller (NIC). It’s a PCI Express-based device used in servers and workstations to deliver 10 Gb/s network connectivity. The suffix B0KMLG identifies the device revision and packaging variant. The card supports standard 10 Gb Ethernet features and hardware offloads (e.g., TSO/LRO, RSS, VLANs, jumbo frames) and works with Broadcom’s bnxt drivers on Linux and Windows. For exact specs (port count, PCIe width, supported media like 10GBASE-T or SFP+, firmware, and driver requirements), consult the official Broadcom product brief or datasheet. In short, BCM57781B0KMLG is a high-speed NIC aimed at data-center/enterprise use to improve throughput and reduce CPU load.
Features
Here are concise features of BCM57781B0KMLG (Broadcom NetXtreme-E PCIe Ethernet controller):
- PCIe interface: PCIe 3.0 x4 host interface.
- Multi-rate Ethernet: supports 1G/2.5G/5G/10G/25GBASE-T with auto-negotiation (speed depends on PHY).
- MAC/PHY: integrated MAC (and PHY options for copper BASE-T).
- Frame handling: jumbo frames up to 9K; advanced offloads (TCP/UDP checksum, LSO/LRO, etc.).
- Traffic acceleration: RSS for multi-CPU scalability; large send/receive offloads.
- Virtualization: VMQ and SR-IOV with support for virtual functions.
- Interrupts: MSI-X/MSI support for performant interrupt handling.
- VLAN/QoS: hardware VLAN offload and QoS features.
- Power/management: ASPM and other PCIe power-management features; Wake-on-LAN.
- Management/OS support: Broadcom drivers for Windows, Linux, VMware/Hyper-V (official support and utilities).
Note: Exact supported speeds and features can vary by PHY configuration and system design.
