How to compile network card driver in OpenWrt?

To compile a network card driver in OpenWrt, you need to follow these steps.

1. To set up the OpenWrt compilation environment, first, you need to follow the instructions in the OpenWrt documentation to download and install the OpenWrt SDK.
2. Choose the driver you want to compile: Based on your network card model, select and download the corresponding driver source code. Typically, network card driver source code is provided by the network card vendor.
3. Add the driver source code to the OpenWrt source code directory by unzipping the downloaded driver source code and copying it into the source code directory of OpenWrt. Typically, the source code directory is located in the package directory of the OpenWrt SDK.
4. Configure driver compilation options by entering the root directory of the OpenWrt SDK and running the command “make menuconfig” to set up the compilation options for the drivers. On the “make menuconfig” interface, you can select the drivers to compile and other relevant options.
5. Compile drivers: After configuring, use the make command to begin compiling the drivers. The compilation process may take some time, depending on your system’s performance and the size of the driver source code.
6. After compiling, you can install the generated driver into the OpenWrt system. The installation process will vary depending on the type of driver and the version of OpenWrt.

The steps mentioned above are general guidelines for compiling network card drivers in OpenWrt. It is important to note that the specific steps may vary slightly depending on the version of OpenWrt and the type of network card driver you are using. We recommend referring to the relevant information in the OpenWrt documentation for more detailed guidance.
