It would be much more useful to indicate where the values are used.
Such a field/parameter could (probably) have the type of the enum.
But, at some point, the compiler might start barfing at that at well.

There are also a whole load of crappy __packed in that header file.
There might be one or two 64bit items on 32bit boundaries but
that can be solved without using __packed.
