[PATCH] net/mlx5: fix crash when using meter in transfer flow

[Khadem Ullah]

Hi Dariusz,

Yes, you are right — I believe this has been fixed since DPDK v24.11 by the commit you mentioned:
https://github.com/DPDK/dpdk/commit/c30b356a4d48542fe99c47aa470afc8cd1ced9f5

Previously, this appeared to be an edge case where a segfault was triggered when a transfer rule was created (even when not using switchdev). But as confirmed, recent versions (v24.11.2 and newer) now correctly return ENOTSUP or a validation error instead of crashing.

I understand that transfer rules are only valid in switchdev mode, and that using them outside that context is unsupported. I encountered the segfault when testing this specific combination, but it seems the issue has been properly addressed now in the latest versions.

Thanks for confirming!

Best regards,
Khadem Ullah
