This section describe how to use and control Interface's options such:
- Starting and Stopping Network Interfaces
- Network Interface Hardware Address
- Network Interface Maximum Transmit Unit
- Network Interface Link State
Configuration
Some parameters should be configured and/or optimized for your project requirements. Please refer to the s ection Network Interfaces Configuration for further details.
Using Network Interface Programming API
Wherever you want to configure or access an Interface option you should include one or many of these files:
| Include file | Description |
|---|---|
| IF/net_if.h | Functions used for Interface API |
| IF/net_if_ether.h | Ethernet Interface's API reference (used with NetIF_Add()). |
| IF/net_if_wifi.h | Wireless Interface's API reference (used with NetIF_Add()). |
API Reference
All Interface APIs are presented in the section Network Interface Functions.
