+Subject: [PATCH] mptcp: add mptcp reset option support
 
-Signed-off-by: Matthieu Baerts <matthieu.baerts@tessares.net>
+The MPTCP reset option allows to carry a mptcp-specific error code that
+provides more information on the nature of a connection reset.
+
+Reset option data received gets stored in the subflow context so it can
+be sent to userspace via the 'subflow closed' netlink event.
+
+When a subflow is closed, the desired error code that should be sent to
+the peer is also placed in the subflow context structure.
+
+If a reset is sent before subflow establishment could complete, e.g. on
+HMAC failure during an MP_JOIN operation, the mptcp skb extension is
+used to store the reset information.
