Parameters
This A pointer to the EFI_SIMPLE_NETWORK instance.
HeaderSize The size, in bytes, of the media header received on the network
interface. If this parameter is NULL, then the media header size
will not be returned.
BufferSize On entry, the size, in bytes, of Buffer. On exit, the size, in
bytes, of the packet that was received on the network interface.
Buffer A pointer to the data buffer to receive both the media header and
the data.
SrcAddr The source HW MAC address. If this parameter is NULL, the
HW MAC source address will not be extracted from the media
header.
DestAddr The destination HW MAC address. If this parameter is NULL,
the HW MAC destination address will not be extracted from the
media header.
Protocol The media header type. If this parameter is NULL, then the
protocol will not be extracted from the media header. See
RFC 1700 section “Ether Types” for examples.
