Notes from Joy Shermin:

The section 5.10.1.1, in Thread V1.1 spec mentions the below statement. If the RLOC does not belong to a neighboring device, the 6LoWPAN layer encodes the 6LoWPAN frame with a 6LoWPAN Mesh Header, sets the V and F bits to ‘1’, the Originator Address field using the local RLOC16, and the Final Address field using the destination’s RLOC16. The hopsLft field of the 6LoWPAN Mesh Header MUST be set to a value greater than the route cost to the destination. The hopsLft field MUST be incremented by one if the device is not an active Router and also MUST be incremented by one if the destination RLOC16 is not that of an active Router. Note that setting the hopsLft field to a value of 14 or less reduces the size of the 6LoWPAN Mesh Header.

Changing to 1.9, as Thread implementation itself may not make into 1.8.
