 (rc=-17) @ 5.18.x

[TLDR: I'm adding this regression report to the list of tracked
regressions; all text from me you find below is based on a few templates
paragraphs you might have encountered already already in similar form.]

Hi, this is your Linux kernel regression tracker.

CCing the regression mailing list, as it should be in the loop for all
regressions, as explained here:
https://www.kernel.org/doc/html/latest/admin-guide/reporting-issues.html

Jaroslav, did you try to revert the change that was suggested to you in
https://lore.kernel.org/all/d993bbb6-e583-5d91-76c0-841cc5da86af@roeck-us.net/
Did it help?

Anyway: To be sure below issue doesn't fall through the cracks
unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking
bot:

#regzbot ^introduced v5.17 to v5.18
#regzbot title net: ice: Error setting promisc mode on VSI 6 (rc=-17) @
5.18.x
#regzbot monitor
https://lore.kernel.org/all/CAK8fFZ68+xZ2Z0vDWnihF8PeJKEmEwCyyF-8W9PCZJTd8zfp-A@mail.gmail.com/
#regzbot monitor
https://lore.kernel.org/all/CAK8fFZ61mQ3AYpdWjWtyUXzrs-RVMW61mBLrjRDXBxB-F9GzbA@mail.gmail.com/
#regzbot ignore-activity

This isn't a regression? This issue or a fix for it are already
discussed somewhere else? It was fixed already? You want to clarify when
the regression started to happen? Or point out I got the title or
something else totally wrong? Then just reply -- ideally with also
telling regzbot about it, as explained here:
https://linux-regtracking.leemhuis.info/tracked-regression/

Reminder for developers: When fixing the issue, add 'Link:' tags
pointing to the report (the mail this one replied to), as the kernel's
documentation call for; above page explains why this is important for
tracked regressions.

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
