staging: fsl-dpaa2/eth: Don't account SWA in tx_data_offset
When configuring the Tx buffer layout, the software annotation size is mentioned, and MC accounts for it when configuring the frame tx_data_offset. No need to handle it in the driver as well. This results in 64B less memory allocated per frame. Signed-off-by: Bogdan Purcareata <bogdan.purcareata@nxp.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
