The devices use a single worldwide regulatory domain, with channels -12-14 (2.4 GHz band) and channels 52-64 and 100-140 (5 GHz band) restricted to -passive operation. Transmission on those channels is suppressed until -appropriate other traffic is observed on those channels. +=============================================================== +Broadcom brcmfmac driver +=============================================================== +- Support for 32 bit Linux kernel, 64 bit untested -Within the driver, we use the fictitious country code "X2" to represent this -worldwide regulatory domain. There is currently no interface to configure a -different domain. -The driver reads the SROM country code from the chip and hands it up to -mac80211 as the regulatory hint, however this information is otherwise unused -with the driver. +Firmware installation +====================== +Copy brcm/bcm4329-fullmac-4.bin and brcm/bcm4329-fullmac-4.txt +to /lib/firmware/brcm (or wherever firmware is normally installed on your +system).
