The NPU/ASIC vendors are not allowing packets to be pushed in Linux, someone needs to work with them to do that.
What exactly is the problem here ? I guess we can agree that Cisco is a company that is out there to make money, others are too but they have a less capitalistic approach to it, more friendly to the community. You are right about one question, who will pay for packets to flow through the kernel ?
