Hm. Doesn't seem to be working. Which data does "TypeInstance" refer to?
To "Instance" in <plugin snmp><data> structure? Then it will not work,
because I have 'Instance "IF-MIB::ifDescr"' there, not "IF-MIB::ifType".
And setting it to "ifType" is a problem, because it's the same string
for all interfaces, and it causes a mess in RRDs written.
