There should be no risk to moving to dscp queuing mode.  Just be
mindful of what to do with unknown DSCP values you may forget to
assign to a queue.

Currently only the 6708, 6716, and the VS-S720 10G ports support dscp
queing and I imagine that it is CoS by default to match the rest of
the blades available in the 6500.
