The trivial way to do it would be to use the same idea as the current
ehca driver: just create a thread for receive CQ events and a thread
for send CQ events, and defer CQ polling into those two threads.
For RX, isn't this basically what NAPI is doing?
Only NAPI seems better, avoiding interrupts completely and avoiding
latency hit
by only getting triggered on high load ...
Does NAPI schedules CQ callbacks to different CPUs or stays the callback
(handling of data, etc.) on the same CPU where the interrupt came in?
