Changes since v2: - fix indendation of a if line in patch 1 (Mat) - avoid useless conditional in patch 5 (Mat) This adds setsockopt support for busypoll + and the various SO_TIMESTAMP variants. To reduce copy&paste, a few helper functions get exported for mptcp sake. Last patch extends the existing setsockopt test case to also cover/enable SO_TIMESTAMP.
