[mrtg] cfgmaker generates wrong config for OpenBSD

[gnpf]

Hi Steve,

I post my answer again, because my first answer is still waiting for aproval
since 2 days, but I think the email was to big. 
So I put the large parts as text files on my webserver.

Yes thats right.

[root at nagios ~]# snmpwalk --version
NET-SNMP version: 5.3.2.2

[root at nagios ~]# cfgmaker --version
cfgmaker for mrtg-2.16.4

I restart the snmpd on all my BSD Systems, without any changes.

I have this Issue on all my OpenBSD Systems. Its not always the same OS and
snmpd Version, so I dont belive that the problem is there. Here are the
whole Informations about a other system, with less interfacese, but the same
trouble:
