> Currently if the driver does a TSO offload the bytecount sent to
> netdev_tx_sent_queue will be incorrect. This is because in ice_tso we
> overwrite the initial value that we set in ice_tx_map. This creates a mismatch
> between the Tx and Tx clean flow. In the Tx clean flow we calculate the
> bytecount (called total_bytes) as we clean the descriptors so the value used
> in the Tx clean path is correct. Fix this by using += in ice_tso instead of =. This
> fixes the mismatch in bytecount mentioned above.
