Change Details

Update ecn tunneling functions to follow RFC 6040. ECN_COMPLETE added to support dangerous packet reporting without causing extra cost to existing caller functions. ECN_ALLOWED updated to follow MUST portion of RFC 6040. consumer could choose between ECN_COMPLETE and ECN_ALLOWED based on their requirements. IPv6 wrappers updated to use IPV6_FLOWLABEL_LEN to guide other developers. finally return values are specified as macro to reduce confusion considering extra return values for ECN_WARN and ECN_ALARM added. note: these changes are necessary for geneve (RFC 8926) implementation.
