mptcp: Use per-subflow storage for DATA_FIN sequence number
Instead of reading the MPTCP-level sequence number when sending DATA_FIN, store the data in the subflow so it can be safely accessed when the subflow TCP headers are written to the packet without the MPTCP-level lock held. This also allows the MPTCP-level socket to close individual subflows without closing the MPTCP connection. Signed-off-by:Mat Martineau <mathew.j.martineau@linux.intel.com> Signed-off-by:
