Hello DPDK Community,

I am currently working with the Intel IAVF driver in a DPDK environment and
have observed that when trust mode is set to off on a Virtual Function (VF),
the corresponding port goes down.

Despite reviewing available documentation and recent DPDK commits, I have n=
ot
found any official references explaining whether this behavior is:

    1. An intended feature related to security or resource management,
    2. A known limitation or side effect when disabling trust mode, or
    3. A bug that may be addressed in future releases.

Additionally, I have looked for changes or bug reports related to the funct=
ion
iavf_dev_alarm_handler or port link state management triggered by trust mode
changes but could not find relevant details.

Could anyone from the community or the DPDK development team please clarify:

    1. Is the port going down when trust mode is disabled a documented and
expected behavior? If so, is there an official reference or documentation
available?
    2. Are there any workarounds or best practices recommended when using t=
rust
mode in production environments?
    3. If this is a known issue or bug, is there a timeline for a fix?

Any insights or pointers to relevant code changes, documentation, or
discussions would be greatly appreciated.

Thank you in advance for your help!

Regards,
Susmitha
