Re: [bcm4329] brcmfmac on kernel 2.6.35 (Andorid)

Hi Renzo,

First of all, is it really a good choice to use a fullmac dongle to do 
the scan algorithm investigation? For brcmfmac, all scanning 
implementation is in dongle firmware which is not open source. There is 
nothing much you can do with it. A softmac pci nic probably can meet you 
requirement.

brcmfmac doesn't have any android support for sure(wake lock, bt coex, 
WIFI_CONTROL_FUNC and etc.).

For ICS we switch to a newer driver bcmdhd which use cfg80211 instead of 
wext. If you want to use cfg80211 instead of wext, this should be a 
better choice.

We do have android support on the roadmap but it's not a high priority 
task because of several reasons.
