Subject: [regression] igc does not function anymore after second resume from
 standby

[Tony, Przemek: lore did not find any mail from Sasha in the past few
weeks, so from here it looks like this might be something somebody else
needs to handle.]

Hi, Thorsten here, the Linux kernel's regression tracker.

Sasha, I noticed a report about a regression in bugzilla.kernel.org that
appears to be caused by this change of yours:
6f31d6b643a32c ("igc: Refactor runtime power management flow") [v6.10-rc1]

As many (most?) kernel developers don't keep an eye on the bug tracker,
I decided to write this mail. To quote from
https://bugzilla.kernel.org/show_bug.cgi?id=219143 :

> Starting with Kernel 6.10.x I experienced network connection
> problems after resuming my system for the second time.
> 
> My system contains two Intel I225-V (rev2 and rev3) cards.
> 
> I ran a bisection and got a hit: 6f31d6b643a32cc126cf86093fca1ea575948bf0
> 
> rmmod igc ; modprobe igc remedies the issue till the next but one resume.

See the ticket for more details. Martin, the reporter, is CCed.

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