[B.A.T.M.A.N.] Switch backhaul based on connection

Hi all,

I have nodes A, B, C. On all nodes, wifi and lan are bridged. Also, they are all connected via mesh.

|---> node B ethernet <--> Node A <-- | | ---> node C

Node A is the exit node - connected via ethernet cable and node B and node C are connected to A via mesh.

So, when I connect node C via ethernet, does it start using ethernet as backhaul or still keeping mesh.

that is, when a client connects via wifi to node C, does the traffic go via option 1 or option 2?

option 1: client wifi <--> node C <--> mesh iface <--> node A <--> router

option 2: client wifi <--> node C <--> ethernet eth0 <--> router

Thanks
