It supports the bcm4329 device which comes with a 11n phy, which can connect to a non-11n AP without problems. > * Does this driver interfaces the mac80211 operations or "acts as" a > mac80211 driver itself talking to cfg80211/nl80211? The brcmfmac does not require mac80211, but interfaces with cfg80211. > * Does the chipset/current implementation support sleep/awake > triggers? (or at least quiet elements?) Nope. All powersaving the device does is done on the device as it knows best what parts of the device can be put to sleep. Who or what is going to fire those triggers? > Thanks for your answer, > Andr?s Hope that helps. Gr. AvS
