mptcp: Track received DATA_FIN sequence number and add related helpers
Incoming DATA_FIN headers need to propagate the presence of the DATA_FIN bit and the associated sequence number to the MPTCP layer, even when arriving on a bare ACK that does not get added to the receive queue. Add structure members to store the DATA_FIN information and helpers to set and check those values. Signed-off-by:Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by:
