Log Message:
changed register for start of dma buffer to be DD_NEXT_INITBUF instead
of DD_NEXT for regular dma transfers, and not just ethernet transmit.
Keep track of dma read/write direction and set it each time we start or
restart dma.  This allows scsi to work, and doesn't appear to hinder ethernet.
