I'm now wondering if we're falling into a terminology trap. The original
tc/cake implementation of 'squash' was effectively to use 'besteffort'
(ie diffserv1) ie. ignore the DSCP bits *and* to clear the DSCP bits on
outgoing 'wash'.
I (foolishly?) split out the DSCP washing feature to a separate
controllable flag - wash/nowash*
Thus it is at present possible to use the DSCP bits for diffserv4/5
differentiation on ingress to the queue but to clear those DSCP bits for
egress purposes.
