event-type
==========
:type: enum
:enum-name: mptcp-event-type
:name-prefix: mptcp-event-


:entries:
    :unspec: unused event
    :created: token, family, saddr4 | saddr6, daddr4 | daddr6, sport, dport A new MPTCP connection has been created. It is the good time to allocate memory and send ADD_ADDR if needed. Depending on the traffic-patterns it can take a long time until the MPTCP_EVENT_ESTABLISHED is sent.
    :established: token, family, saddr4 | saddr6, daddr4 | daddr6, sport, dport A MPTCP connection is established (can start new subflows).
    :closed: token A MPTCP connection has stopped.
    :announced: token, rem_id, family, daddr4 | daddr6 [, dport] A new address has been announced by the peer.
    :removed: token, rem_id An address has been lost by the peer.
    :sub-established: token, family, loc_id, rem_id, saddr4 | saddr6, daddr4 | daddr6, sport, dport, backup, if_idx [, error] A new subflow has been established. 'error' should not be set.
    :sub-closed: token, family, loc_id, rem_id, saddr4 | saddr6, daddr4 | daddr6, sport, dport, backup, if_idx [, error] A subflow has been closed. An error (copy of sk_err) could be set if an error has been detected for this subflow.
    :sub-priority: token, family, loc_id, rem_id, saddr4 | saddr6, daddr4 | daddr6, sport, dport, backup, if_idx [, error] The priority of a subflow has changed. 'error' should not be set.
    :listener-created: family, sport, saddr4 | saddr6 A new PM listener is created.
    :listener-closed: family, sport, saddr4 | saddr6 A PM listener is closed.
