The value of tSapEgressMatchCriteria indicates which type of match
criteria the policy should use.
When tSapEgressMatchCriteria has a value of 'ip', the sap-egress
policy looks for match entries in tSapIngressIPCriteriaTable
or tSapIngressIPv6CriteriaTable.
The value of tSapIngressMatchCriteria is set when the first match criteria
table entry is created. The value of tSapEgressMatchCriteria is set to
'none' when the last criteria table entry is removed.
