It would be need to have a backport sent stable@vger.kernel.org . Once
it lands in the older stable series, we can include it as well
downstream in Debian. What does Pablo say on the backport for the
older series? I see it has been applied to 5.15.17 and 5.16.3, but is
not yet queued for older series.

Let's CC Pablo and Florian.

Pablo, Florian, Steffen is asking for a fix as well back to 4.19.y to
address the issue fixed in mainline with 4e1860a38637 ("netfilter:
nft_payload: do not update layer 4 checksum when mangling fragments").
Do you know will it be picked up as well for the older stable series
affected?

Regards,
Salvatore
