Recent update seems to have broken 1500 MTU on PPP #8

It looks like a recent update has changed something in the way the UDM is initializing the PPP connection. Running the same script as normal, I'm ending up with both the PPP and Ethernet interface at 1500 (not ETH at 1508), which as expected breaks a lot of things.

If I manually up the eth connection to 1508, the PPP connection seems to establish fine, pulls all the IP(6) addresses, but the UDM pretty quickly kills it again - i'm not entirely sure why looking at the logs.

Happy to share any logs if this helps - I'm not quite sure how to track this down as it seems that all is set as it should be.

I can confirm, on the UDM-SE.
