21.3. Driver compilation and testing
Refer to the document compiling and testing a PMD for a NIC for details.
21.4. Limitations or Known issues
Currently, we only support VF device is bound to vfio_pci or igb_uio and then driven by DPDK driver when PF is driven by kernel mode hns3 ethdev driver, VF is not supported when PF is driven by DPDK driver.
Build with ICC is not supported yet. X86-32, Power8, ARMv7 and BSD are not supported yet.
