What is decAtmMasterLinecardSlot?

Identifies which slot currently holds the active master line card in a chassis with redundant controllers; a value of 0 means no master has been elected yet, or the chassis has no such concept. Admins check this to confirm which physical slot is actively running the switch fabric before pulling a card for maintenance.
