Initially 802.3 doesn't support multiple upper layer protocol
e.g. IP,IPx,AppleTalk etc. But as need arise to support
multiple upper layer protocol, Ethernets L2(Data Link)
broken into Two Parts....<1> LLC <2> MAC
<1> LLC introduced a additional field in ethernet frame to
distinguished between multiple upper layer protocol
802.3 uses S_SAP and D_SAP to identify multiple upper layer
