<dd><p>This option prevents the library from sending PING frame with ACK
flag set automatically when PING frame without ACK flag set is
received. If this option is set to nonzero, the library won’t send
PING frame with ACK flag set in the response for incoming PING
frame. The application can send PING frame with ACK flag set using
