Regarding napi_tx switching, this patch set is not only compatible with the previous way of using tx-frames to switch napi_tx, but also improves the user experience when setting interrupt parameters. This patch set has been tested and was part of the previous netdim patch set[1] and is now being split to be rolled out in steps.
