Description: A table of serial GBIC information, indexed by device and port. Only GBIC-based devices must implement this table. Each port of a GBIC-based device will have a corresponding row, regardless of whether or not the port contains a serial GBIC; if the port does not contain a serial GBIC or if the serial GBIC information has not yet been fully read, then the value of gbicEntryValid is 'invalid'.

The gbic device platforms requires a certain minimal level of firmware to support serial GBIC information. The FeatureMask object indicates whether or not this feature is supported via the SGBIC bit. If this feature is not supported on a given device, then the gbicEntryValid object will have the value 'invalid' for all ports on that device.
