That's what I was waiting for. I took a look into the mrtg-2.9.28 and I
expected a bit of increased readability....
My simple pacth was only concerned with operative iusses, not
documentation ones.
So yours is more complete !

Another interesting contribution : your mrtg-2.9.28 was succesfully tested
on
	SuSE-8.0

against:
	-  a PC-box running net-snmp
	-  HITACHI GR2000 10-H router  ( They are SNMP IPv6 enabled !!)

You were rigth. I did not apply the "--enableipv6" flag. When applied  it
uses to run , ...

OK, we will  test your new patch and installing it from
a final user's approach.  See who the program reacts when you ask for IPv6
and you have no support... things like that...


BTW, concerning design iussues, about the "IPv4only" way ( routers like
Cisco, processing IPv6, but not supporting SNMP IPv6 ).

Do you keep this iussue ? Maybe it make the code a bit more complicated
and can be avoided, in order to reduce the code again. You can always ask
for IPv6-MIB entries from IPv4, as
the old MRTG use to do.

But it's up to you. I have no deep knowledge on your code.

Congratulations again.
