How to discriminate between SSH and SCP for QoS?
It seems the highest matching QoS takes effect, make sure not to have a general rule for port 22/SSH around: OpenWRT by default ships a rule matching SSH and DNS together. For there rules, I used the overlapping DSCP values of 0x04 and 0x02 as proposed in the quora post linked above.
