PATH
The Open Transport CSMA/CD driver recognizes three packet formats. They are Ethernet, 802.2, and Novell "Raw 802.3," a version of IPX. The details of the packet format are largely hidden from the client by the driver.
The type of packets the driver will handle is specified at bind time.
In all three packet formats, the first 6 bytes are the destination hardware address, and the next 6 bytes are the source hardware address. The first 6 bytes are followed by a protocol-dependent section, followed by the packet data.
The packet formats that the DSMA/CD driver can handle are diagrammed in Figure 14-1.
