I have a worry that as soon as our kernel does conversion from one
priority classification, to a different level's priority conversion,
we should possibly be responsible for doing some traffic management
automatically.

My gut feeling is we should be the same rate limiting back-pressure
that downstream devices do.

If we don't have that... hey, can I get a trivial knob to make my chrome
set the DSCP_EF flag?  Or can we make that the default?

See, I'm saying there is a slippery slope to EF becoming the default,
and I feel like that should be stopped by saying high priority obviously
means a limited % of traffic on the port.
