Description:

- TestInetEndPoint was not hermetic, it required at least one network
  interface connected to a link and up.
- There was a comment before to skip tests if the link was not up,
  but it was not actually skipping the test. This made it fail for
  me when working offline and trying to run unit tests.

Testing done:
- Test passes with and without link up.
