====================
net: qrtr: Add distant node support

QRTR protocol allows a node to communicate with an other non-immediate
node via an intermdediate immediate node acting as a 'bridge':

node-0 <=> node-1 <=> node-2

This is currently not supported in this upstream version and this
series aim to fix that.

This series is V2 because changes 1, 2 and 3 have already been submitted
separately on LKML.

Changes in v2:
- Add reviewed-by tags from Bjorn and Mani
- Fixing checkpatch issue reported by Jakub
