Hi,

One possible condition to get -ENOTSUP is if DevX is disabled on the NIC,
Have you verified DevX is enabled  ?
Please check here :
https://doc.dpdk.org/guides/nics/mlx5.html
---
enable DevX (required by Direct Rules and other features):
UCTX_EN=1
---

With higher log verbosity, you could check in the application
initialization if mlx5 PMD returns"DevX is supported" to make sure.

Regards,
Erez
