Re: [LARTC] how to add my own traffic scheduler to TC

["Roy" <roy@xxx.lt>]

TC is like iptables, you need to add suport to tc binary for your module,
else you wont be able to configure it.
I dont know how to do this , but try to find some analogy with other modules
you will need to modify tc makefile, and add aditional module.
