The DPAA Ethernet doesn’t work anymore on our FSL P5020/P5040 boards [1]
since the first updates after the final kernel 6.1 [2].
We bisected yesterday [3] and found the problematic commit [4]. I was
able to revert it. After that the DPAA Ethernet works again. I created a
patch for reverting the commit [4]. After patching and compiling, the
DPAA Ethernet also works again.

It seems, that the new driver doesn’t work with our onboard DPAA network
interfaces.

Could you please check your commit? [4]

Thanks,
Christian

Thanks for the report. To be sure the issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, the Linux kernel regression
tracking bot:

#regzbot ^introduced 5d93cfcf7360
#regzbot title lnet: dpaa: Ethernet issues
#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 and tell me -- ideally
while also telling regzbot about it, as explained by the page listed in
the footer of this mail.

Reminder for developers: When fixing the issue, add 'Link:' tags
pointing to the report (see page linked in footer for details).

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