Hi, 
This section needs to be replaced to match with the actual steps for meson: 

Initialization
--------------

In order to enable this virtual bbdev PMD, the user may:

* Build the ``FLEXRAN SDK`` libraries (explained in Installation section).

* Export the environmental variables ``FLEXRAN_SDK`` to the path where the
  FlexRAN SDK libraries were installed. And ``DIR_WIRELESS_SDK`` to the path
  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 DIR_WIRELESS_SDK=<path-to-workspace>/FlexRAN-FEC-SDK-19-04/sdk/build-avx2-icc/
    cd build
    meson configure -Dflexran_sdk=<path-to-workspace>/FlexRAN-FEC-SDK-19-04/sdk/build-avx512-icc/install

* 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.
