Thanks a lot for adding the test. Could you replace nc with socat or a similar tool? There are multiple incompatible implementations of netcat packaged by various distros, we get:
# selftests: net: busy_poll_test.sh # nc: invalid option -- 'N' # Ncat: Try `--help' or man(1) ncat for more information, usage options and help. QUITTING.
nc is a known PITA.
- # set the suspend parameter for the server via its IFIDX
- DUMP_CMD="${YNL_PATH} --spec ${SPEC_PATH} --dump napi-get --json="{\"ifindex\": ${NSIM_DEV_1_IFIDX}}" --output-json"
- NSIM_DEV_1_NAPIID=$(ip netns exec nssv bash -c "$DUMP_CMD")
- NSIM_DEV_1_NAPIID=$(echo $NSIM_DEV_1_NAPIID | jq '.[] | .id')
- SUSPEND_CMD="${YNL_PATH} --spec ${SPEC_PATH} --do napi-set --json="{\"id\": ${NSIM_DEV_1_NAPIID}, \"irq-suspend-timeout\": 20000000, \"gro-flush-timeout\": 50000, \"defer-hard-irqs\": 100}""

Can you try to run this test in installed mode?

IIRC YNL moves around when we install, you'd either need to do autodetection of the path (see tools/testing/selftests/net/lib/py/ynl.py and if you go down this route please move the helper which exports the YNL variables to lib.sh so other tests can reuse); or teach the C code to do the setup, you can link against YNL fairly easily (look at where ncdevmem is added in the Makefile, it uses YNL)
