where the libraries were extracted.
+* Tune the meson build option pointing the location of the FlexRAN SDK
libraries ``flexran_sdk``

Example:
.. code-block:: console
export
FLEXRAN_SDK=<path-to-workspace>/FlexRAN-FEC-SDK-19-04/sdk/build-avx2-icc/install
export

+* For AVX512 machines with SDK libraries installed then both 4G and 5G can be
enabled for full real time FEC capability.
+ For AVX2 machines it is possible to only enable the 4G libraries and the PMD
capabilities will be limited to 4G FEC.
+ If no library is present then the PMD driver will still build but its
capabilities will be limited accordingly.
-* Set ``CONFIG_RTE_BBDEV_SDK_AVX2=y`` and ``CONFIG_RTE_BBDEV_SDK_AVX512=y``
- in DPDK common configuration file ``config/common_base`` to be able to use
- the SDK libraries as mentioned above.
- For AVX2 machine it is possible to only enable CONFIG_RTE_BBDEV_SDK_AVX2
