	The IEEE 802.11 spec define a ad-hoc cell where all the nodes
can talk to each other (fully connected topology). 802.11 would not
support your example, you would end up with cell splitting (i.e. two
different BSSID).
	That's why HostAP offer WDS, where you can establish point to
point links and route between them. You can then use any routing
protocol you wish.
