Ethernet Layers Interactions

This The sections that follow describe the interactions between the IF layer, the Ethernet device driver API functions, the BSP API functions and the Ethernet PHY API functions. Since the device driver is not only made of not only logic but also from interactions with the parts on the board, you'll need to understand the calls made to the these layers of the µCµC/TCP-IP module and to the CPU and board-dependent layers.

Figure 7-5 The figure below shows the logical path between the physical layer and the device driver through the function calls and interruptions.
