The MaximumMessageSize property indicates the maximum message size supported by the protocol. This is the maximum size of a message that can be sent from or received by the host. For protocols that do not support message framing, the actual maximum size of a message that can be sent to a given address may be less than this value. There are two special values defined for this property:
0  - The protocol is stream-oriented; the concept of message size is not relevant.
1  - The maximum outbound (send) message size is dependent on the underlying network MTU (maximum sized transmission unit) and hence cannot be known until after a socket is bound. Applications should use getsockopt to retrieve the value of SO_MAX_MSG_SIZE after the socket has been bound to a local address.
 0xFFFFFFFF - There is no specified maximum message size defined.
