I still think squashing is very important, and essentially required by several rfcs.
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.
