<pre class="bz_comment_text">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 not
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 function
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 trust
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
