These line lengths look uneven. The html generator tool would not generate it like that. If I run `make update-build-docs` I get a diff on these lines. Please make sure the html files you are committing are exactly what the tool would generate to avoid creating diffs for the next person editing these files.

Suggestion:

you should install the SCTP library before running the tests.


Also please fix line breaks so line lengths are uniform and match the rest of the file.
