The protocols supported by the Plugs Library adhere to the standards
recommended by the RFCs at http://www.ietf.org.
The Nios EDK supports Ethernet and 802.3 packets. To send an 802.3
packet, the application has to construct all fields explicitly. Higher-level
protocols do not support 802.3, and uses Ethernet instead. Nios EDK does
NOT support trailer encapsulation as documented in RFC 893.
The library routines send and receive Ethernet packets to and from
arbitrary 48-bit MAC addresses. Higher-level protocols such as ICMP,
UDP, and TCP use Ethernet transparently.
