tSapIngressMacCriteriaActionFC specifies the forwarding class
or the sub forwarding class to be used to classify all the
traffic that matches the specific Mac criteria.
Specification of a sub forwarding class is also allowed. The
format of a sub forwarding class is the concatenation of the
base forwarding class and a sub class identifier in the form
base-fc-name[.sub-fc-name]
To reference a sub forwarding class, the mapping of the sub
forwarding class should be existing in this QoS policy.
Unless tSapIngressMacCriteriaActionFC is specified explicitly,
this match will be ignored for classification purposes.
