BCM57781B0KMLG

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.

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.

Pin count: 1514 pins (LGA package KMLG).
Function: Broadcom NetXtreme II PCIe Ethernet controller (10-Gigabit Ethernet NIC with MAC/PHY).

- Manufacturer: Broadcom Inc.
- About the company: Broadcom is an American multinational semiconductor and infrastructure software company that designs and sells a wide range of chips for networking, data centers, wireless, and storage, and also provides enterprise software solutions. It is largely fabless, meaning it designs chips and outsources fabrication to foundries.

BCM57781B0KMLG uses an LGA (land-grid-array) package. For exact ball count and dimensions, refer to the official datasheet.
