Note:
For an official description of an Ethernet packet, refer to IEEE 802.3 specification, Figure
3-1.
The descriptor table contains three entries: the next pointer (NP), the packet size
(Pkt_Size) and the packet status (Stat), as illustrated in
NP is a 24-bit pointer to the start of the next packet. Pkt_Size contains the number of bytes
of data in the Ethernet packet, including the four CRC bytes, but does not contain the
seven descriptor table bytes. Stat contains the status of the packet. Stat differs for Transmit
and Receive packets. See
