+Subject: [PATCH 1/1] DVMRP report missing subnet
+
+Accepted upstream and will be included in 3.9.8.
+https://github.com/troglobit/mrouted/commit/512af5ffe0f48ffa2ba3b45898c66c2a561a5c2d
+
+A subnet is missing in the DVMRP report sent to it's neighbor after
+the initial probe occurs.  The issue was with the traversal of a double
+linked list from end to start. Once the traversing pointer reaches
+the start of routing table for loop (condition) it would break and
+always drop the first subnet.
