Patches 1 and 5 do some cleanup in checksum option parsing and clarification of lock handling. Patches 2 and 3 rearrange struct mptcp_options_received to shrink it slightly and consolidate frequently used fields in the same cache line. Patch 4 optimizes incoming MPTCP option parsing to skip many extra comparisons in the common case where only a DSS option is present. ==================== Signed-off-by: David S.
