So - question : is there any way, when returning from rtl8169_poll, to tell napi something like : " finish this interrupt context and let something else run on this CPU (always CPU0 on my machine) BUT reschedule another napi poll on this same device at some time after that "
Does the hardware support any options for interrupt mitigation? I've used some devices where you can specify a minimum time between interrupts such that even if NAPI re-enabled interrupts and there were packets waiting the hardware would wait a certain time before raising a new interrupt.
