This article explains how net devices are mapped to the Linux® kernel netdevice stack.
1. Purpose
This article introduces the Linux® kernel netdevice. Its purpose is to provide to newcomers some first insights regarding networking. The other articles referenced in this page provide detailed information about each component connected to netdevice.
2. System overview
The netdevice stack is used for 3 purposes:
- CAN,
- Ethernet
- and Ethernet switch. (Only applicable for STM32MP25x)
In articles, referenced just above, for each network items, more information is given on :
- configuration
- How to use framework
- how to trace and debug
- source code location
- to go further
Linux® community offers several links to help understanding the netdevice stack:
