Fast handoff at L2

First of all i want to mention that i have gone through IEEE 802.11
standard, 802.11f standard, and particular parts of 802.11i standard.
I have also read all HostAP readme and hostap/iapp.c and developer.txt
I want to implement fasthandoff at L2 by different techniques, and also
use the that information in 802.11i, though that description is not very
much clear, but i guess is sufficient in asking following questions.
So here are the questions:
1. Is it possible to scan(actively or passively) just subset of
channels? if yes then how?
2. If I want to implement neighbor graph learning(only neighbor learning
from re-association frames and nothing else because i don't need IP
addresses of APs just the IBSS(MAC) address so i dont need any RADIUS
module or static IP address to MAC address table or anything else.), i
guess i have to do that in hostap/iapp.c code, but particularly what
functions/code-files to use for that or from where to start studying in
whole hostAP code.
3. If i want to implement neighbor graph learning at the client side, i
guess i have to do that in hostAP driver code, but again in that code
particular which functions/code-files are useful for this or if at least
you can give a hint that where to start looking/studying code in hostAP
driver for this task.
As above questions are totally developer question so I humbly request
Jouni and other developers on this forum to answer and guide me properly
in this regard.
I have done only application C/C++ programing on windows environment
before and know very little about driver or kernel level programing, but
very ambitious to learn it.
