At least for eepro100, the receive interrupt mitigation doesn't exist in the
driver.  There were some changes about TX completion interrupts, but I
consider them as rather irrelevant.

The other question is that it's possible to turn on hardware interrupt
mitigation on Intel's chips by uploading a microcode.
Intel's driver claims to do it.

Best regards
