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.

Yes, please refer to the register 0xE2 of datasheet. And the time is influenced
by the register 0xE0.
