Running fips sample app with aesni_mb and SHA ACVP test vector files. Also occurs with QAT. 
./dpdk-fips_validation --vdev=crypto_aesni_mb -- --req-file $FIPS_DIR/$alg/req --rsp-file $FIPS_DIR/$alg/resp_aesni_mb --path-is-folder

Output shows invalid memory bug.
EAL: Detected CPU lcores: 64
EAL: Detected NUMA nodes: 2
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'VA'
EAL: VFIO support initialized
EAL: Using IOMMU type 1 (Type 1)
CRYPTODEV: Creating cryptodev crypto_aesni_mb
CRYPTODEV: Initialisation parameters - name: crypto_aesni_mb,socket id: 0, max queue pairs: 8
IPSEC_MB: ipsec_mb_create() line 168: IPSec Multi-buffer library version used: 2.0.0
EAL: Error: Invalid memory

SHAKE is not supported by these hence I did not catch it.

Thanks, 
Emma
