This reports the next available connection-entry index (link ID) that can be used when creating a new row in hh3cMinmConnectionTable for this VSI, ranging from 0x1 to 0xFFFFFFFF. A management application reads this value before creating a connection entry, since it must be supplied as the new entry's link ID, and the invalid value 0xFFFFFFFF means no connection entry can currently be created (also returned when vsiShareConnection is set and hh3cVsiIndex is not 1). For example, reading a value of 5 tells the manager to use link ID 5 as the index for the next connection entry it creates under that VSI.
