[collectd] Unable to SNMP collect two-dimensional(?) table

[Mark]

Stian,
  Octo has been working on a patch that he wrote for the SNMP plugin that I
believe will fix this. I ran into the same issue anytime I was trying to
collect SNMP data from dynamically created MIB entries. The SNMP plugin
expects MIBs to increment sequentially at the last "octet" of data. This
isn't always the case with tables - especially when the table entry itself
may contain other table entries. His patch fixes this.
