A number of applications that are based on the DPDK like OVS and other vswitch applications,
require for their correct use, very high flow insertion rate.
In current implementation each flow is downloaded to the device using RDMA-Core, Kernel and FW.
The main bottleneck is the FW.
The solution is to use a new SW lib (located in RDMA-Core) which will bypass the FW and insert the flows directly into the device.
This will improve the insertion rate from 4K rules per seconds to over 200K rules per seconds.
The PMD will be backward compatible with previous RDMA-Core by selecting the APIs to use according to the RDMA-Core version.
Most changes should be in the mlx5_flow_dv engine. Where calls to mlx5dv_xx will be replaced by mlx5dv_dr_xx
