tmnxCpmIcPortSFFStatus

The TmnxSFFStatus specifies the operational status of the small form
factor (SFF) that is inserted into the port. If the SFF is removed
from the port, the value of TmnxSFFStatus will be 'not-equipped (0)',
otherwise 'operational (1)' if no failure is detected.
          
A failure to read the SFF data will result in a 'read-error (2)',
while corrupted information on the SFF will result in either
'data-corrupt (3)', or 'ddm-corrupt (4)' if an SFF read results in
invalid data or DDM information respectively.  An insertion of an
unsupported SFF will result in 'unsupported (5)'. An insertion of
an SFF device that is preventing other devices from being read will
result in the state 'culprit (6)' for the offending device, and
'blocked (7)' for the other devices.  Some transceivers can report
faults and this is reflected in the 'fault' status.
Some connectors can physically accept different transceiver form
factors but operationally only support a subset of those form factors
For these connectors, unsupported transceivers will result in the
state 'invalid-form-factor'.
          
A trap will be raised if the value of TmnxSFFStatus indicates a
failure; that is the TmnxSFFStatus is neither 'not-equipped (0)', nor
'operational (1)'.
