Old devices are supported by 15 the b43legacy driver. 16 Note that this has nothing to do with the standard that your AccessPoint 17 supports (A, B, G or a combination). 18 IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints. 19 20 It is safe to include both b43 and b43legacy as the underlying glue 21 layer will automatically load the correct version for your device. 22 23 This driver uses V4 firmware, which must be installed separately using 24 b43-fwcutter. 25 26 This driver can be built as a module (recommended) that will be called "b43". 27 If unsure, say M. 28 29config B43_BCMA 30 bool "Support for BCMA bus" 31 depends on B43 && BCMA 32 default y 33 34config B43_SSB 35 bool 36 depends on B43 && SSB 37 default y 38 39# Auto-select SSB PCI-HOST support, if possible 40config B43_PCI_AUTOSELECT 41 bool 42 depends on B43 && SSB_PCIHOST_POSSIBLE 43 select SSB_PCIHOST 44 select SSB_B43_PCI_BRIDGE 45 default y 46 47# Auto-select SSB PCICORE driver, if possible 48config B43_PCICORE_AUTOSELECT 49 bool 50 depends on B43 && SSB_DRIVER_PCICORE_POSSIBLE 51 select SSB_DRIVER_PCICORE 52 default y 53 54config B43_PCMCIA 55 bool "Broadcom 43xx PCMCIA device support" 56 depends on B43 && SSB_PCMCIAHOST_POSSIBLE 57 select SSB_PCMCIAHOST 58 ---help--- 59 Broadcom 43xx PCMCIA device support. 60 61 Support for 16bit PCMCIA devices. 62 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA 63 devices, but 32bit CardBUS devices.
