iperf3 new iperf for ssr

	Client	windows server
	iperf3 -c 10.1.4.10 ( default port 5001 )	iperf3 -s
1M of bandwidth	iperf3 -c 10.1.4.10 -b 1m	iperf3 -s
TCP maximum segment size (MSS) MSS of 100 ( did not work	iperf3 -c 10.1.4.10 -b 1m -M 100	iperf3 -s
	The MSS is usually the MTU - 40 bytes for the TCP/IP header. The MSS is 1460 bytes (1500 byte MTU of the IP packet, or 1514 for ETH packet size).
different port	iperf3 -c 10.1.4.10 -b 1m -M 100 -p 5123 iperf3 -c 10.1.4.10 -b 1m -M 100 -p 5124	iperf3 -s -p 5123 iperf3 -s -p 5124
UDP	iperf3 -c 10.1.4.10 -b 1m -M 100 -u	iperf3 -s -u
Small Vs Big packets
