Consistent hash load balancing on FTIs

This feature enables consistent hash load balancing on flexible tunnel interfaces (FTIs). During load balancing, when the number of ECMP paths crosses the threshold, the server fails and results in traffic skewness. With consistent hashing, you can avoid skewness of the flows toward initial set of ECMP paths. Only the flows for paths that are inactive are redirected. Flows mapped to servers that remain active are maintained.
