Hello, I have a problem. When I execute this command snort --daq-dir /usr/local/lib/daq --daq dpdk --daq-var dpdk_args="-c 3" -i dpdk0:dpdk1 --daq-mode inline -c /etc/snort/snort.conf -Q -f 'not ip', I will output the following prompts.

I tried to specify the .so file for all drivers in the Makefile, but it failed. When testing the testpmd and l2fwd demo, rte_eth_dev_count() returns > 0, and these problems do not occur.
I would appreciate if you could give me some advice. Thank you!
