doesn't involve generating
other interrupts using hrtimers etc. :) Initial results are very
encouraging in my setups. Would you be willing to test it with eHEA? I
don't have a 10G setup. If results are encouraging, I'll post an RFC to
ask for review / feedback from the NAPI

If NAPI disables interrupts and keeps them disabled wh
s, while minimizing packet processing latency. No need for hardware
interrupt mitigation.
