Networking Overview


On STM32MP1 Series, the netdevice stack is used for two purposes: CAN and Ethernet. A more detailed block diagram of each interface is available in dedicated pages: CAN and Ethernet.
Linux® community offers several links to help understanding the netdevice stack:

  • Kernel networking flow [1],
  • Kernel networking documentation[2]
