Description
This function writes a UDP packet specified by the (optional
parameters to the network interface. The UDP header is automatically built by this routine. It uses
the parameters OpFlags, DestIp, DestPort, GatewayIp, SrcIp, and
this header. If the packet is successfully built and transmitted through the network interface, then
will be returned. If a timeout occurs during the transmission of the packet, then
EFI_SUCCESS
will be returned. If an ICMP error occurs during the transmission of the packet,
EFI_TIMEOUT
then the
