FddiTime, and update to Path config table

[Anil Rijsinghani <[e-mail]>]

    A small update on the Path Config Table I sent out last week:
    the PATHConfResourceCurPath is an enumerated type now,
    and should be one of: isolated(1), local(2), secondary(3), primary(4),
    concatenated(5), thru(6).

    On a different topic: at the meeting last week, we spoke about
    possibly going to a more usable time unit than 80 nsec units.
    After speaking with some people here, it appears that 1 microsecond
    units would be both more readable and sufficiently granular for all
    objects that use this syntax.  Unless there are objections, I
    propose that FddiTime be changed to 1 usec units.

    thanks,
    Anil
