If a packet has reached its intended destination, it was bumped to the code that accepts it, without first checking if a mesh_path needs to be created based on the discovered source. Fix this by moving the destination address check further down Signed-off-by: Felix Fietkau <nbd@nbd.name>

that accepts it, without first checking if a mesh_path needs to be created
|
|
based on the discovered source.

Fix this by moving the destination address check further down
