The tmnxBsxGrpStatusIngQTable contains an entry for each
ISA-AA MDA and Group in the system. Each row contains the
Qos status information for traffic exiting an ISA-AA MDA
given the tmnxBsxGrpStatusInQDirection and
tmnxBsxGrpStatusInQIndex. An ISA-AA MDA is uniquely
identified by the tmnxChassisIndex, tmnxBsxCardSlotNum, and
the tmnxMDASlotNum.
