That's a completely useless comment. Obviously, everybody uses NAPI; it's necessary for system load and thus performance, and lets drivers take advantage of TCP merging to reduce ACKs, which is tremendously helpful (over wifi in particular.) Please stop making such drive-by comments that focus only on the single thing you find important above all; not all people can care only about that single thing, and unconstructively reiterating it over and over doesn't help.
