OVS DOCA uses DOCA api as an HW offload layer for the flow insertion to HW while the datapath remains the same as with OVS DPDK.
As mentioned in the manual, to use DOCA offload for the flow insertion you will have to set an additional parameter “doca-init=true” in addition to “dpdk-init=true”.
With DOCA enabled on top of DPDK, the flow insertion is done via the doca flow api instead of rte_flow.
