Android employs a Wifi-HAL layer in its wireless frame. It basically

to be able to have a generic nl80211 Wifi-HAL implementation. One of
the features currently requiring the vendor commands is g-scan. We
can only guess what the 'g' stands for ;-) This series converts the
vendor command api into common nl80211 api.

Hehe :)
We also have gscan API. If you're interested, you can see it here:

Before making an attempt to explain more about the g-scan
functionality first this. While I am still testing the driver
implementation resulting in numerous questions Dmitry send the email
below to bring a related discussion to the table..eh.. the linux-
wireless list. This is probably a good thing as anyone can dive in
and share their thoughts.

Yeah. How does this overlap? Have you looked at it already?
