The kernel was tested on 2 instances below is my testing transcript

1. Enable proposed on one of the VMs
2. Install linux-image-generic, which installed kernel 5.4.0-132.148
3. Rebooted the node, and was able to set the IP, and ping another VM
4. Set the MTU to 9000, and was still able to ping the other VM
5. On the second VM, changed the MTU 9000 (this still had old kernel), and the ping stopped. The error in dmesg was there as per the first comment
5. Upgraded the kernel on the second VM from proposed, and rebooted the VM
6. Ping started, when the second VM came up
7. Set the MTU to 9000, and the ping still continued

The same steps were repeated with setting the MTU in netplan, and we didn't have any issues
We also tested an MTU of 1550, to go outside of the standard 1500 and 9000, and we didn't see any issues either
