Get rid of that one too. It's better do not have that extra
complication.
By the way, I think we can hide the handle of extended and enhanced
control fields inside the macros to get control bit fields. So we won't
have to care about that in the code. We still have to talk about that.

It depends. If we have few occurrence of that macros, they could be in
same patch.
