This read-only value reports the next available connection entry index that would be used when creating a new connection entry for this MAC-in-MAC virtual switch instance (VSI), ranging from 0x1 to 0xFFFFFFFF, with 0xFFFFFFFF meaning no new connection entry can be created; if the device's vsiShareConnection capability is set and this VSI's index isn't 1, this object returns the invalid value. Admins read it before creating a new entry in hpnicfMinmConnectionTable, using its value as the required link ID for that new row. For example, an admin provisioning a new backbone connection for a VSI would first read this object to obtain the correct link ID to use, then use that value as the index when creating the new connection table entry.
