SNMP::Info determines what SNMP objects to query for each device, eg to 
determine the os_ver.

Looks like all three IBM switch models are classified as 
SNMP::Info::Layer3::IBMGbTor devices, which always requests the object 
IBM-GbTOR-10G-L2L3-MIB::agSoftwareVersion.0 
(.1.3.6.1.4.1.26543.2.7.4.1.1.1.10.0) to determine the software version.

The IBM-GbTOR-10G-L2L3-MIB in netdisco-mibs however seems specific to 
the G8124 model.

What MIBs should be used for models other than the G8124 ? They would 
have to be included in netdisco-mibs and SNMP::Info has to be updated to 
use the correct MIBs and objects for each model.
