Arbitrary length of packet may be received from network, including the packets with zero payload data or malformed protocol header. So the code much check the actually received data size before using it. For example, in current edk2 network stack, an zero payload UDP packet may cause the platform ASSERT in NetbufFromExt() because of the zero fragment number. This patch update the IpIoLib and UdpIoLib to check and discard the zero payload data packet to avoid above assert. Some other network drivers are also updated to check the packet size to guarantee the minimum length of protocol header is received from upper layer driver.
