This chip is connected via sdio, and has a built in ARM7TDMI CPU alongside with RAM and (some kind of) ROM. The WLAN stack runs inside this CPU. The host communicates with this device like with an standard ethernet card (albeit with some extensions). If the device was an usb device, this would be called CDC (communcation device class), her it is called DCH (whatever...) There is a modified CDC driver in the kernel to support similar broadcom usb cards. the b43 driver does support broadcom cards without this embedded cpu (connected via PCI...) and does implement the functions of the embedded code of the embedded cards on the x86 host cpu. So this driver is orthogonal to b43 > Maybe > including LP-PHY? Or 802.11n devices?
