TCP socket creation and multiplexing/demultiplexing.
A single instance of this class is held by one instance of class Node.
The creation of TcpSocket are handled in the method CreateSocket, which is called by TcpSocketFactory. Upon creation, this class is responsible to the socket initialization and handle multiplexing/demultiplexing of data between node's TCP sockets. Demultiplexing is done by receiving packets from IP, and forwards them up to the right socket. Multiplexing is done through the SendPacket function, which sends the packet down the stack.
Moreover, this class allocates "endpoint" objects (ns3::Ipv4EndPoint) for TCP, and SHOULD checksum packets its receives from the socket layer going down the stack, but currently checksumming is disabled.
ns3::TcpL4Protocol is accessible through the following paths with Config::Set and Config::Connect:
TypeId

No TraceSources are defined for this type.
Size of this type is 144 bytes (on a 64-bit architecture).

Destructor implementation.
This method is called by Dispose() or by the Object's destructor, whichever comes first.
Subclasses are expected to implement their real destruction code in an overridden version of this method and chain up to their parent's implementation once they are done. i.e, for simplicity, the destructor of every subclass should be empty and its content should be moved to the associated DoDispose() method.
It is safe to call GetObject() from within this method.

Setup socket factory and callbacks when aggregated to a node.
This function will notify other components connected to the node that a new stack member is now connected. This will be used to notify Layer 3 protocol of layer 4 protocol stack to connect them together. The aggregation is completed by setting the node in the TCP stack, link it to the ipv4 or ipv6 stack and adding TCP socket factory to the node.
