Works with 3120 blade switches for HP

The OID for stack state (1.3.6.1.4.1.9.9.500.1.2.1.1.6) can return Integer:11 which does not have appropriate entry in %STACK_STATES.
According to

http://tools.cisco.com/Support/SNMP/do/BrowseOID.do?objectInput=1.3.6.1.4.1.9.9.500.1.2.1.1.6&translate=Translate&submitValue=SUBMIT

after line 45, one more line should be added:

’11’ => ‘removed’

With this change (and the one pointed out by tt-ts), it works great. Thanks!
