    The bug fixes depend on the cleanups.
    * 1/7 has the new functions.
    * 2/7 has bug fixes that require the new functions.
    * 3/7 fixes (and optimizes) the incoming code path, so that
    * 4/7 can fix the bugs.
    * 5/7 is needed to test the code from part 1.
    * 6/7 is the cleanup of parsing (also fixes some bugs introduced by
    davem's patch in December), so that
    * 7/7 can fix the bugs.

    I originally tried submitting these as separate individual pairs of
    patches (in November, December, January), but nobody paid any attention.
