The 'tc' semantics seem to support this "pretty bad" API design
with many of the fields already duplicated. I suppose we could
put the flags at the same level as the TCA_* attributes but this
also doesn't seem right to me as it isn't actually handled until
we get into the TCA_#CLASSIFIER#_* set of attributes.
