From d27e77a3de2866b0a772803fd03cd667b5ff8a9a Mon Sep 17 00:00:00 2001 From: Arun Kumar Neelakantam Date: Wed, 4 Jul 2018 19:49:33 +0530 Subject: [PATCH] net: qrtr: Reset the node and port ID of broadcast messages All the control messages broadcast to remote routers are using QRTR_NODE_BCAST instead of using local router NODE ID which cause the packets to be dropped on remote router due to invalid NODE ID.
