Subject: sr-iov related bonding regression (two regressions in one report)

Hi Thorsten and all,

I come across LACP bonding regression on Bugzilla [1]. The reporter
(Cc'ed) has two regressions. The first is actual LACP bonding
regression (but terse):

> Till linkx kernel 6.5.7 it is working fine, but after upgrading to 6.6.1 ping stop working with LACP bonding.
> When we disable SR-IOV from bios , everything working fine

And the second is out-of-tree module FTBFS:

> Also we are not able to compile 
> driver: ice
> version: 1.12.6
> We are getting following error.
>

> With inter driver code(version 1.12.6) while complaining I am getting following error.

Should I add the first regression to regzbot (since the second one
is obviously out-of-tree problem), or should I asked detailed regression
info to the reporter?

Thanks.
