e1000e and NAPI

Hi, we have some applications that receive very high packet rates, and
have not noticed the behavior I would expect from NAPI (as I
understand it). Does the e1000e driver support napi? If so, wouldn't I
see the number of interrupts (as measured with sar) go down with a
high packet rate (say, >100k). Right now, with interrupt moderation
off for the card I'm seeing virtually 1:1 wrt packets and interrupts.

Thanks
