[c-nsp] 6500 Sup 2T QoS

[Christopher Pole]

Figured this out finally, the equivalent is to set queue-limit percentages
under the class, and the order is important as the second trail drop
threshold is not configurable. E.g.:

  class c-map-af31-af32-af33
    bandwidth remaining percent 10
    queue-limit dscp values af32 af33 percent 80
queue-limit dscp values af31 percent 100

Will work but the following will not (and will not spit out any kind of
error):

  class c-map-af31-af32-af33
    bandwidth remaining percent 10
    queue-limit dscp values af31 percent 100
queue-limit dscp values  af32 af33 percent 80

Hopefully this will help if someone else has this issue.
