Ok, my bad again. Used a text editor to change the patch, as the change is
minor, and worked before I skipped the checkup with fuzztest.

But I ran the fuzztest and utils on the original version of the patch, so it
shouldn't matter

There are parts of the openSAFETY specification, which are prepared to be put
inside the stack, but are not actually in it yet. They will be in future
versions, and then I will put the codes into dissector.

So, they basically exists as a reminder for me.

I will add some to the SampleCaptures page on Monday, as I do have them at my
office. Is this the same method to add them to regression testing and automatic
fuzz testing? If not, please tell me how, to add the files.

kind regards
