[ovs-dev] Question about DPDK + OVS in high level

I am new to DPDK.

The purpose of DPDK is to bypass kernel layer when it forwards to user

My first question is how DPDK works with OVS.
Since OVS has two tables in user space and kernel space, the second packet
is matched in kernel tables after one packet is missed and controller
inserts correct flow.
In this case, DPDK is not very effective.
Or with DPDK, entire kernel table is not used?

Does DPDK with OVS implement tunneling like GRE?
