As titled said, we're going to refine the NOT_SPECIFIED reason in the
tcp v4/6 receive fast path.

This serie is another one of the v2 patchset[1] which are here split
into six patches. Besides, this patch is made on top of the previous
serie[2] I submitted some time ago.

1. change the title of 2/2 patch.
2. fix some warnings checkpatch tool showed before.
3. use return value instead of adding more parameters suggested by Eric.
