I have nodes A, B, C and all are mesh.
Node A is the exit node - connected via ethernet cable on eth0 and
node B and node C are connected A via mesh.
So, when I connected 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?
client wifi <--> node C <--> mesh iface <--> node A <--> router
client wifi <--> node C <--> ethernet eth0 <--> router
