Next-filter as a firewall filter action

Firewall filters can be configured to execute a sequence of firewall filter actions. The new next-filter option allows you to deploy a filter list and run a series of filters, similar to what is already available with next-term actions, and provides filter scale optimization. Up to eight filters can be chained in this way. The feature is not supported on logical systems, or on loopback and pseudointerfaces. You can use a filter list to implement a mix of multifield-classification and firewall filter rules. For example, the first filter in the list can be used to perform a generic filter classification, and the subsequent filters can then do the actual filtering.
