+ * recv: Check if the hardware received a packet. If so, set the pointer to the
+ * packet buffer in the packetp parameter. If not, return an error or 0 to
+ * indicate that the hardware receive FIFO is empty. If 0 is returned, the
+ * network stack will not process the empty packet, but free_pkt() will be
+ * called if supplied
+ * free_pkt: Give the driver an opportunity to manage its packet buffer memory
+ * when the network stack is finished processing it. This will only be
+ * called when no error was returned from recv - optional
+ * stop: Stop the hardware from looking for packets - may be called even if
+ * state == PASSIVE
+ * mcast: Join or leave a multicast group (for TFTP) - optional
+ * write_hwaddr: Write a MAC address to the hardware (used to pass it to Linux
+ * on some platforms like ARM). This function expects the
+ * eth_pdata::enetaddr field to be populated. The method can
+ * return -ENOSYS to indicate that this is not implemented for
+ this hardware - optional.
+ * read_rom_hwaddr: Some devices have a backup of the MAC address stored in a
+ * ROM on the board. This is how the driver should expose it
+ * to the network stack. This function should fill in the
+ * eth_pdata::enetaddr field - optional
