Introduction

The R3 release will evaluation the throughput and packet forwarding performance of the Mellanox BlueField SmartNIC card.

...

our own offload code which enables the full hardware offload with DPDK rte_flow APIs. 

We have plans to open-source this OVS-DPDK. More detailed details will be provided in the future documentation.
