That's something I haven't seen.  However, I'm only using rx-frames=1
because simply adjusting rx-usec doesn't behave as expected.  (It's
documented, but perhaps only in the ethtool source, that rx-frames=0
means to use just rx-usec, which is what you want to be able to adjust
the coalescence as suggested.)
