Hello,
Please consider backporting to 4.9.y the following commit from DaveM
[CC'ed]:
f4eb17e1efe538d4da7d574bedb00a8dafcc26b7 ("Revert "sit: reload iphdr in ipip6_rcv"")
It cherry-picks cleanly and builds fine.
The original commit was introduced and reverted in v4.12-rc5, but only
the original made its way into the 4.9 stable release (v4.9.94).
It causes a regression: pings to v6 hosts over a SIT tunnel do not work
anymore, and the following error appears in dmesg:
kernel: sit: non-ECT from 0.0.0.0 with TOS=0xd
This was also reported and reverted downstream by Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1772775
Thanks!

Kind regards,
Luca Boccassi
