how to run test 80211s

Hi

i have six nodes running 80211s.
I want to run some tests, forcing various logical topology over the mesh
network, and take a look on how 80211s react to network topology changes.
I thogut it was a good idea (e.g.) to kill conectivity between adjacent mesh
nodes simply discarding (somehow) packets between those nodes to force the
mesh to reconfigure paths.

At first I tried using ebtables, to force packet-drop upon mac addresses
rules, with no luck, mesh nodes still see full mesh connections.

I am trying iptables now, but can't still find a working set of rules.

[Let's say i work with three nodes A---B---C and want to kill mesh
connection between A and C:
$ iptables -t mangle -A PREROUTNIG -m mac -mac-source xx:xx:xx:xx:xx -j DROP
on node A where xx is C mac address]

I am wondering if any of you can share any ideas on how i can manage to run
these tests.

I know there are working commands (iw ...) but those commands work directly
on 80211s mpath, and this is not what i want.

Hope i made myself clear, thanks in advance for your time.
