No I meant I've seen it saturate a Ge link (with sufficiently large frames).

With very small frames the tx rate gets limited to a nice round number.
Possibly because the usb message rate limit.
It is high enough that it really doesn't matter, the code could put multiple
frames in a single URB, but I'm not sure the NAPI processing loop makes that
easy.

The receive side will run at a higher packet rate.
