i'm new to kernel, so this question is dummy.

but how to change default gateway inside kernel code,
e.g. my network device driver ?

thanks !

You probably don't want to modify the kernel itself, but merely use the route command to modify the runtime routing behavior.

Code:

man route

If you really mean to modify the kernel, then my best suggestion is to dig into the kernel sources. <your-kernel>/net/ipv4/route.c looks like a good place to start.
