Use DSCP for IP QoS traffic classes
The previous TOS values are deprecated and not used by modern traffic
classifiers. This sets AF21 for "interactive" traffic (with a tty).
Non-tty traffic sets AF11 - that indicates high throughput but is not
lowest priority (which would be CS1 or LE).
This differs from the CS1 used by OpenSSH, it lets interactive git over SSH
have higher priority than background least effort traffic. Dropbear's settings
here should be suitable with the diffservs used by CAKE qdisc.
