And this is not an overlay. It is all there at boot?

I was just thinking that maybe the Ethernet interface gets opened at
boot, and overlay is loaded, and the interface is opened a second
time. I don't know of anybody using DSA with overlays, so that could
of been the key difference which breaks it for you.
