    - patch DPDK for O-RAN FHI lib, this patch is specific for O-RAN FHI to reduce the data transmission latency of Intel NIC. This may not be needed for some NICs, please refer to O-RAN FHI Lib Introduction -> setup configuration -> A.2 prerequisites

Right now there is no open source driver available yet, so you need to get the associated vendor's driver to enable the capability to use an accelerator card.
