You can find the (layer-2) neighbors using the
iwpriv msh0 fwt_list_neigh n
command. Combining that information with a (persistent) ARP table can give
you the IP addresses.
The mesh TTL field will eventually be tunable on a per packet basis.

That is a global setting though, and not something we want applications
Is there a way for a program to figure out which of a list of ip
addresses are neighbours in the mesh (i.e. 1 hop away)?
