+ * 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 - optional
+ * read_rom_hwaddr: Some devices have a backup of the MAC address stored in a
