-Vector PMD
-~~~~~~~~~~
-
-Vector path for Rx and Tx path are selected automatically.
-The paths are chosen based on 2 conditions:
-
-- ``CPU``
-
- On the x86 platform, the driver checks if the CPU supports AVX512.
- If the CPU supports AVX512 and EAL argument ``--force-max-simd-bitwidth``
- is set to 512, AVX512 paths will be chosen.
-
-- ``Offload features``
-
- The supported HW offload features are described in the document cpfl.ini,
- A value "P" means the offload feature is not supported by vector path.
- If any not supported features are used, cpfl vector PMD is disabled
- and the scalar paths are chosen.
