if that's the only issue, then preventing one from compiling with both SMP
and DEVICE_POLLING doesn't seem necesary, since you can turn polling on
and off at runtime with sysctl's.
As I stated in my first letter it seems that polling on SMP w 4.10 is not
working as expected. At least with i82550 chipset.
With best regards, Oleg Gawriloff.
