This feature comprises two parts:

To extend Traffic Steering to Nexthop Groups (GRE) by allowing us to specify one or more nexthop groups of type DzGRE (DANZ GRE) as the destination for a TAP aggregation steering policy. A DzGRE header will be encapsulated to the packets sending out a nexthop group of type DZGRE.

To extend GRE Tunnel Termination by allowing decapsulation of traffic received from nexthop groups of type DZGRE and adding VLAN tags based on DZGRE metadata.

This feature enables Tap Aggregation generic header removal on a tap port.

This feature extends the capabilities of Tap Aggregation traffic steering to allow for using interface traffic policies. Initially, interface traffic policies only allowed packet drop, count, qos (set traffic class, set dscp) and log actions.
