Re: RFC4941bis implementations

I thought for the privacy extension VL PL changes as the final changes in
the discussion as we went through so many permutations and many threads
just so I am clear from what I recall.

So what was on the table was VL=2 PL=2.   Then for a balance of issues with
long lived flows using invalid address and trying to reduce the number of
deprecated addresses as far down as possible that can exist to help with
MTTR troubleshooting we decided on finally VL=PL=2.

Reduces the default Valid Lifetime for temporary addresses:
      The default Valid Lifetime for temporary addresses has been
      reduced from 1 week to 2 days, decreasing the typical number of
      concurrent temporary addresses from 7 to 2.  This reduces the
      possible stress on network elements (see Section 4
<https://tools.ietf.org/html/draft-ietf-6man-rfc4941bis-09#section-4>
for further
      details).

Thanks
