Log: MFC r365547: Add -z "TOS" option to ping6, to test DSCP/ECN values ping has the option to add the (deprecated) TOS byte using the -z option. Adding the same option, with the same (deprecated) Traffic Class Byte (nowadays actually DSCP and ECN fields) to ping6 to validate proper QoS processing in network switches.
