e1000e: Add interrupt moderation run-time ethtool interface
The ethtool -c / -C interface can now be used to modify the irq moderation algorithm. This change does not require an adapter reset and can thus be used at all times. The adapter only supports changing/reading rx-usecs which has special values for 0, 1 and 3: 0 - no irq moderation whatsoever 1 - normal moderation favoring regular mixed traffic (default) 3 - best attempt at low latency possible at cost of CPU For values between 10 and 10000 the rx-usecs defines "the minimum time between successive irqs" in usec, unlike the module parameter.
