Then, I figure a udev rule should do. Something like this (untested:)

ACTION=="add", SUBSYSTEM=="net", KERNEL!="lo", RUN+="/usr/bin/ethtool $name ..."

Replace the "..." of course with the ethool options you need.

This would then be run immediately when the device appears. If this
makes a measurable difference, then let us know.
