What were you trying to do that didn't work?

The dpdk bbdev run failed with the turbo_dec and ldpc_dec file on ACC100 card

Please provide the package NVR for which bug is seen:

kernel 5.14.0-427.13.1.el9_4.x86_64
dpdk-23.11-1.el9.x86_64
dpdk-tools-23.11-1.el9.x86_64

How reproducible:

Steps to reproduce

1. Run the dpdk bbdev test
2. pf_bb_config acc100 -p 0000:5e:00.0 -v 56ce457d-e2a9-49b1-8e9b-2d6e14cf56f9 -c /usr/share/pf-bb-config/acc100/acc100_config_vf.cfg
3. echo 16 > /sys/bus/pci/devices/0000:5e:00.0/sriov_numvfs
4. dpdk-test-bbdev -a0000:5f:00.0 --vfio-vf-token 56ce457d-e2a9-49b1-8e9b-2d6e14cf56f9 – -c validation -v /tmp/tmp.Blsbsly7Xf/turbo_dec_c1_k40_r0_e17280_sbd_negllr.data

Expected results

It run dpdk bbdev successfully with using the turbo_dec or ldpc_dec file

Actual results

It has no issue with dpdk-22.11-4.el9, it only has issue with dpdk-23.11-1.el9. The throughput, latency and validation all test types are have issue with dec file.
