it compiles and should work. Some code-style rewriting was done, but there

macros DSDEF, DSCUR, etc for major readability of data sets code

code was pruned from specific "ptp-proposal" protocol and the
skeleton of IEEE-1588 states was made. Next step is to insert,
step by step, the structs defined in ptpd. Still something needs
to be removed or renamed, but this should be a fair starting point.
