I don't think each driver should be doing its own checksum helper. It should be done at application or through libraries. All modern hardware does checksum offload, so if it doesn't probably a driver bug. > > Add txpollnotrdy devarg (default=true) to control whether poll() > is called when the TX ring is not ready.

Don't do two things in one patch. Not sure if some variant of the existing configure thresholds could be used for this. > Signed-off-by: Scott Mitchell <[email protected]>
