[PATCH] tests: add a test for mesh forwarding

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Johannes Berg <johannes.berg@xxxxxxxxx>

Add a new test that tests connectivity between two stations that
can't reach each other directly in the mesh, but need forwarding
on another station to talk to each other.
