yongari 730fb9d66a TSO engine of L1 requires a separate DMA descriptor for TCP ... payload. This means driver has to split a TX buffer into two pieces of TX buffers when the TX buffer contains both ethernet/IP/TCP header and partial TCP payload. The controller does not require all header should be in a TX buffer but driver forced it to compute IP/TCP header size/offset which is required parameter to configure DMA descriptor for TSO. While here, slightly reorder DMA descriptor setup to enhance readability and remove unnecessary code for TSO(upper stack never requests TSO when the frame length is less than or equal to MTU).
