Probably you are using software time stamping. If so, you need to
increase neighborPropDelayThresh. Read the ptp4l.8 man page, and you
will find:

   neighborPropDelayThresh
          Upper limit for peer delay in nanoseconds. If the estimated peer
          delay is greater than this value  the  port  is  marked  as  not
          802.1AS capable.
