to stop the transmissions. This parameter is ignored in the case of
Continuous mode of transmission.
<delay>: Delay between packets in Burst mode. This parameter is used
to introduce a delay between any two packets. The delay has to be
specified in microseconds. If this value is 0, then the packets will be
transmitted without any delay. This parameter is ignored in the case of
Continuous mode of transmission.
