Since all current drivers supports Tx preparation API, it is used in csum forwarding engine by default for all drivers. Adding additional step to the csum engine costs about 3-4% of performance drop, on my setup with ixgbe driver. It's caused mostly by the need of reaccessing and modification of packet data.
