Restricted traffic over raw sockets

Detailed description
A very small number of Windows applications make use of raw IP sockets,
which provide an industry-standard way for applications to create TCP/IP
packets with fewer integrity and security checks by the TCP/IP stack. The
Windows implementation of TCP/IP still supports receiving traffic on raw IP
sockets. However, the ability to send traffic over raw sockets has been
restricted in two ways:
·	TCP data cannot be sent over raw sockets.
·	UDP datagrams with invalid source addresses cannot be sent over raw
sockets. The IP source address for any outgoing UDP datagram must exist on a
network interface or the datagram is dropped. 

Why is this change important? What threats does it help mitigate?

This change limits the ability of malicious code to create distributed
denial-of-service attacks and limits the ability to send spoofed packets,
which are TCP/IP packets with a forged source IP address...."
