Yes, to me it's perfectly fine to add this function here, or could even
be a more generic tcp_conn_state($conid), retuning a value that mirrors
the corresponding enum (+1 for the >= 0 values):

enum tcp_conn_states { S_CONN_ERROR=-2, S_CONN_BAD=-1,
  S_CONN_OK=0, /* established (write or read) */
  S_CONN_INIT, /* initial state (invalid) */
  S_CONN_EOF,
  S_CONN_ACCEPT, S_CONN_CONNECT
};
