Description (partial)

GRE tunnel interface is showing huge counters after removing the GRE tunnel interface and adding the configuration of the interface  back.

Create a GRE/mGRE tunnel and send traffic so that packet/byte counters show non-zero stats. Now unconfigure and configure the tunnel (using same tunnel index). This causes the packet/byte counters for the tunnel to show abnormally large garbage values.
