DSCP values are dropped on egress

[hwoesner]

If you google for 'DSCP trust' you will find various discussions around this. Apparently there is a general configuration that a switch removes DSCP bits while a router should pass them unchanged.
So it may be more of a missing feature, or a broader discussion if there should be a "default switch" or "default router" configuration in BISDN Linux.
The "default switch" would then, for instance, create the swbridge and bind ports to it, while the "default router" would pre-configure router settings like the above.

I guess the points here would then be 1) document that BISDN Linux comes with this DSCP trust feature disabled by default, and 2) have DSCP trust configurable in the switch as a feature. Still, I do find odd that a plain L2 bridge configuration ends up with this behavior by default.
