There are two drivers for this chip AFAIK.
lsmod | grep cfg80211 and see if it outputs
This is open-source driver which comes in the kernel so it should work out of the box. But in some case you may need to blacklist
bcma module first. If you are not using it by default in order to give it a try do
sudo modprobe -r wl && sudo modprobe brcmsmac
OR if the above command doesnot give you anything
sudo modprobe -r bcma ssb wl && sudo modprobe brcmsmac
This is the additional driver you are talking about provided by the package
broadcom-sta-common. You can test it the same way as above just do.
sudo modprobe -r brcmsmac bcma b43 && sudo modprobe wl

/etc/modules. So if you would like to use say
wl you would add
/etc/modprobe.d/blacklist.conf and add
This is a pretty good documentation on broadcom drivers.
