What is usdSmdsMajorIfLowerIfIndex?

This read-create value gives the ifIndex of the interface that a major SMDS interface is layered over, with zero indicating no layering. Some implementations may require a nonzero value be supplied when the row is created. An admin would set this to the ifIndex of the underlying carrier interface, such as a DS3 port, when provisioning the major SMDS interface.
