running dpdk on mellanox with dpdk 21.08

[animesh tripathi]

Hi Cliff,

The earlier error is resolved now. It was some compilation problem. Now I
am getting some other error:

EAL: Detected 24 lcore(s)
EAL: Detected 1 NUMA nodes
EAL: Auto-detected process type: PRIMARY
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/nr_dpdk/mp_socket
EAL: Selected IOVA mode 'PA'

EAL: Driver cannot attach the device (0000:b5:00.1)

Can you please help me in resolving this error.
