The data-path object representing dropping the packet.

Definition at line 22 of file drop_dpo.c.

const char* const drop_ethernet_nodes[]

Initial value:

const char* const drop_ip4_nodes[]

static

Initial value:

}

The per-protocol VLIB graph nodes that are assigned to a drop object.

this means that these graph nodes are ones from which a drop is the parent object in the DPO-graph.
