The sample CC performance conf is faulty, as the client cannot receive packets

[gasxia]

client conf:

dperf/test/performance/cc/client/client-cc-port1-1.conf

Lines 13 to 17 in 1d22958

	#port pci addr gateway [mac]
	port 0000:01:00.0 6.6.245.3 6.6.245.1 b4:a9:fc:ab:7a:85
	# addr_start num
	client 6.6.245.3 100

The client is configured with 100 IPs, but only one port is configured, and cannot receive packets back other than the port-bound IP.
The socket was not successfully established and could not continue sending packets on the socket, and the socket on the server side was closed after a timeout.

Another problem is that this configuration does not match the documentation.

It is due to my local network environment that the client did not receive the packet back, the configuration is fine.

dperf will take over all the IPs in the client's configuration.
