It can support the bifurcation model without unbinding the kernel driver, by utilizing our private kernel driver in conjunction with rdma-core. Currently, our kernel driver is not open-source, so it is considered a private kernel driver. This patch series only supports the VFIO driver. Our kernel driver is currently in the process of being open-sourced on kernel.org, and once it is available there, we also plan to submit the code that supports our kernel driver to DPDK. -- Best regards, Renyong Wan
