@Jain True..
I can't see any real use case outside the fully proprietary, private cloud sold to you by VMWare..
Offloading tasks to the NIC is a thing which is useful. But the concept from Nvidia is just wrong.
I can't do software-defined networking when I need to rely on a router which is on the hardware 😅 (bound to one single server)
If I have networking stuff that exceeds the limits of software-defined networking, I go cheaper by actually getting real hardware routers.
