e1000: allow ethtool coalesece to adjust interrupts per second
This patch allows on-the-fly adjustment of the interrupts per second generated by e1000 devices 82545/82546 (hardware support of ITR register is a requirement) adjust using this command: ethtool -C eth0 rx-usecs 10 where 10 is 10 microseconds per interrupt interval, so 10 = 100,000 interrupts per second, and 125 = 8000 interrupts per second. changes should be immediate. 1,3 are special values and indicate the automatic tuning mode to the driver, where 1 is 4000-90000 interrupts per second and 3 is 4000-20000 interrupts per second and is the driver default.
