I appears that this academic is very good at public relations. They mix interrupts and polling depending on the load. The interrupt service routine and user-kernel context-switch overhead is tiny computationally and hence in power usage. Also, most network hardware in the last twenty years has had buffer coalescing, reducing interrupt rates.
