The 9118 ethernet controller supports transmission of multi-buffer packets with arbitrary byte alignment of the start and end bytes. All writes to the packet fifo are 32 bits, so the controller discards bytes at the beginning and end of each buffer based on the 'Data start offset' and 'Buffer size' of the TX command 'A' format. This patch uses the provided buffer length to limit the bytes transmitted. Previously all the bytes of the last 32-bit word written to the TX fifo were added to the internal transmit buffer structure resulting in more bytes being transmitted than were submitted to the hardware in the command. This resulted in extra bytes being inserted into the middle of multi-buffer packets when the non-final buffers had non-32bit aligned ending addresses.
