For users of i40e, seems this depends on the following host patch where the
max_mtu from the host PF that is now used was not set on i40e (but was for ice).

It's also queued for stable. We may want to pull this at
The patch has now made it upstream into the v6.0-rc7 release:
https://github.com/torvalds/linux/commit/399c98c4dc50b7eb7e9f24da7ffdda6f025676ef
It has also been pushed to the stable-queue for the upstream 5.4 and 5.15
kernels:

Been working with Trent and Intel, and below [1] is the patch for the

My test kernels are available in PPA [2] for both 5.4 and 5.15

With MTU=1550 or MTU=9000 it fails even with the upstream 5.19 kernel
and these patches. So seems we need to report and
Also, this will be resolved in Kinetic via 5.19 and Jammy 22.04.2 via
HWE.
