Hi,

I am trying to configure dpdk on my laptop and get "no probed ethernet
devices" in dpdk-testpmd utility:

laptop :: ~ % sudo dpdk-testpmd -l 0-1 -n 4 --log-level=debug -- -i
EAL: Detected CPU lcores: 8
EAL: Detected NUMA nodes: 1
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
testpmd: No probed ethernet devices
Interactive-mode selected
testpmd: create a new mbuf pool <mb_pool_0>: n=155456, size=2176, socket=0
testpmd: preferred mempool ops selected: ring_mp_mc
Done
testpmd> ...

Checked that dpdk 23.07 supports this my NIC at
http://doc.dpdk.org/guides/rel_notes/release_23_07.html:
