A TCP socket which sends a data packet with CE flags set for test 3.
The SendDataPacket function of this class sends data packet numbered 1 with CE flags set and also doesn't set CWR flags on receipt of ECE flags for test 3. This is done to verify that DCTCP receiver sends ECE only if it receives CE inspite of sender not sending CWR flags for ECE
