Those are ``TCPAOGood``, ``TCPAOBad``, ``TCPAOKeyNotFound``, ``TCPAORequired`` and ``TCPAODroppedIcmps``. +For monitoring purposes, there are following TCP-AO trace events: +``tcp_hash_bad_header``, ``tcp_hash_ao_required``, ``tcp_ao_handshake_failure``, +``tcp_ao_wrong_maclen``, ``tcp_ao_wrong_maclen``, ``tcp_ao_key_not_found``, +``tcp_ao_rnext_request``, ``tcp_ao_synack_no_key``, ``tcp_ao_snd_sne_update``, +``tcp_ao_rcv_sne_update``.

If a segment has a TCP-AO header, the filters may also include +keyid, rnext, and maclen.
