Yes and we will try to go with this approach, to have a user space application that contains the state machines and then in the kernel to extend the netlink messages to map to the switchdev API. So we will create a new RFC once we will have the user space and the definition of the netlink messages. > > Yet your argument for kernel, not user space, is you are worried about > the parameters which need to be passed to the hardware offload engine. > In order to win the argument for a kernel solution, we are going to > need a better idea what you think this problem is.
