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_BCMA_EXTRA 35 bool "Hardware support that overlaps with the brcmsmac driver" 36 depends on B43_BCMA 37 default n if BRCMSMAC 38 default y 39 40config B43_SSB 41 bool 42 depends on B43 && SSB 43 default y 44 45# Auto-select SSB PCI-HOST support, if possible 46config B43_PCI_AUTOSELECT 47 bool 48 depends on B43 && SSB_PCIHOST_POSSIBLE 49 select SSB_PCIHOST 50 select SSB_B43_PCI_BRIDGE 51 default y 52 53# Auto-select SSB PCICORE driver, if possible 54config B43_PCICORE_AUTOSELECT 55 bool 56 depends on B43 && SSB_DRIVER_PCICORE_POSSIBLE 57 select SSB_DRIVER_PCICORE 58 default y 59 60config B43_PCMCIA 61 bool "Broadcom 43xx PCMCIA device support" 62 depends on B43 && SSB_PCMCIAHOST_POSSIBLE 63 select SSB_PCMCIAHOST 64 ---help--- 65 Broadcom 43xx PCMCIA device support. 66 67 Support for 16bit PCMCIA devices. 68 Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA 69 devices, but 32bit CardBUS devices.
