Hello Daniel,
No problem with the delay in the answer. I'm doing far worse.
Here is an updated version:
- add if_link.h in uapi and remove the definition
- fix a commit message
- remove uapi from a include

exports a set function that takes the type in parameter.

It is not correct to assimilate the elf data of the maps section
to an array of map definition. In fact the sizes differ. The
offset provided in the symbol section has to be used instead.
