Hi Thomas, 
What you are referring to was resolved with that previous serie https://patches.dpdk.org/project/dpdk/list/?series=5093&state=*
The turbo_sw_pmd is built by default now and is verified by the DPDK CI. As an option this can be built against the real time signal processing libraries (FlexRAN FEC SDK). The link to latest version of this library is also provided https://software.intel.com/en-us/articles/flexran-lte-and-5g-nr-fec-software-development-kit-modules>

I believe that you reviewed this scheme previously earlier Ferruh of the Tech board as you did provide feedback on the related published article as well as recommended to split the previous serie into several patchsets. 
The last serie under review here in that email thread is the extension of the turbo_sw_pmd driver to support 5GNR operations but still rely on the exact same model and dependency, the only limitation is that these libraries requires AVX512 support for 5GNR operations. 

Let me know whether there is any discrepancy and want to discuss further through that mailing list, tech board or other method. In case you are trying to compile the SDK and have any issues let us know as well. 

Talk to you soon, 
Thanks and regards, 
Nic
