This represents a conditional operation flag -whereby the DSCP is only restored if the flag is set. This is useful to -implement a 'one shot' iptables based classification where the -'complicated' iptables rules are only run once to classify the -connection on initial (egress) packet and subsequent packets are all -marked/restored with the same DSCP.
