The hard-wired configuration of the top speed (until now S800) was unnecessary, remove it. If the local link layer controller supports S1600 or S3200, we now assume this speed for all present 1394b PHYs (except if they are behind 1394a repeaters) until nodemgr figured out the actual speed while fetching the config ROM.
