Are you even aware that the ethtool layer gets invoked by simply
enabling IP forwarding or bridgining, in order to disable LRO
offloading which conflicts with such uses?

And I disagree with your asserion that the tool doesn't get installed
by default by distros.  I can't find one single system here that
doesn't have /usr/sbin/ethtool available.

I guess it depends upon your definition of "various".
