Assuming we use tc_index to provide the hash...

- we don't need to worry about any definitions. tc_index already stands for
  some kind of index grouping together various packets.
- we can directly use sfq to do fair queueing on dscp values and skb
  priority including specialized map with a underlying dsmark or cls_tcindex.
