Any interface to access tc flower from another kernel module?

I was looking at linux tc flower source code. I see that when a flow is modified, a netlink message is sent from user space to kernel space to create/delete/modify the flow. Rather than the userspace triggering those, I would like my kernel module (which I'm building) to do the same. But I don't find any interface to access tc flower functions. Almost everything is defined statically.

So, is there any interface to access tc flower kernel functions from another kernel module?

Hi dpaks,

Welcome!

Tc flower accesses kernel functions. If you want to access those same functions, then follow the code. But I doubt that tc-flower has an api to use it to access the kernel functions it accesses.

Thanks, AwesomeMachine. I have already gone through its code. I e-mailed some of the people who have pushed that code asking the same question but I didn't receive any response yet.

Most of the tc flower functions are static. I need to access the functions that implements the tc flower operations. So, I need a confirmation that there isn't any API to access them.

Do you have any clue as to why the devs kept tc flower so closed?
