Its comment says that the mac layer is supposed to use it but I couldn't find where. Of course, the fact that the abbreviation ends like half of the word in english "-ed" does not help grepping for that, but I could not figure out how useful this callback was. In particular since it is mandatory to provide. I am pretty sure I missed something, so perhaps someone has a pointer to help me there. Thanks a lot! Miqu=C3=A8l
