Broadcom Bcm94312hmg Driver

The BCM94312HMG (chipset BCM4312) was widely deployed in late-2000s laptops (Dell Latitude, HP Compaq). Broadcom never released complete open-source specifications, forcing Linux distributions to rely on the proprietary broadcom-sta driver. The open-source b43 project partially supports the chipset but requires extraction of proprietary firmware.
