v6: Rework total_num_queues in separate commit. Fix typo in comment.
v5: Created separate commit for doc fix. Cosmetic uppercase changes.
v4: Targeting 24.03. Updated FPGA PMD based on review comments.
v3: Made changes requested during review.
v2: Targeting 23.11. Update in commits 1,2 based on review comments.
v1: Targeting 23.07 if possible. Add support for AGX100 (N6000) and corner case fixes.
Hernan Vargas (6):

Rename generic functions and constants using the FPGA 5GNR prefix naming
to prepare for code reuse for new FPGA implementation variant.
No functional impact.

+The test application ``test-bbdev.py``, supports the ability to configure the PF device with
+a default set of values, if the "-i" or "- -init-device" option is included. The default values
+are defined in test_bbdev_perf.c as:

+- VF_UL_QUEUE_VALUE 4
+- VF_DL_QUEUE_VALUE 4
+- UL_BANDWIDTH 3
+- DL_BANDWIDTH 3
+- UL_LOAD_BALANCE 128

Thanks, that's all good.
The next-baseband PR for -rc1 will be ready once github actions run has
completed:
