Each tmnxBsxCflowdStatusEntry contains the Cflowd
status information for a particular group, Cflowd export
type and ISA-AA MDA.
An index with a valid tmnxBsxIsaAaGroupIndex and a valid
tmnxBsxCflowdExpType, tmnxChassisIndex set to one,
and a zero value for each of the tmnxBsxCardSlotNum/tmnxMDASlotNum
indices will return the summarized per group status.
