[Olsr-users] [B.A.T.M.A.N.] point me to some OSI layer diagramsif possible ?

I thought 802.11s need not be strictly layer 2. Open source 11s driver
is on top of MAC drivers that comply with mac80211 framework.
So it can be either layer 2 or 2.5.

Sorry, but that is not (entirely) correct. It is no problem calling
a layer 2 protocol for the sake of simplicity (it deals with MAC
instead of IP addresses, etc ..). But if you mention batman-adv and
802.11s/ath5k/etc in the same sentence you have to be more precise as
not operate on the same layer.
batman-adv is layer 2.5 and runs on top of all ethernet based layer 2
protocols which means you can run it over wireless
(managed/adhoc/mesh/whatever mode), plain ethernet cable, VPNs and so
However, 802.11s is "true" layer 2 and as such is limited to the medium
(wireless) as well as to the hardware & drivers.
