Does PetaLinux support 1G/10G/25G Switching Ethernet Subsystem

I need a fast 10G ethernet in my system but I also want backwards compatibility with 1G ethernet. I have been experimenting with the 10G/25G High Speed Ethernet Subsystem and a 10GBASE-T SFP module (haven't got it fully working yet but that's a different story...). As this IP aparently doesn't support 1G ethernet, I switched the design to 1G/10G/25G Switching Ethernet Subsystem.

After switching I noticed that petalinux doesn't load a driver. Looking at the device tree,  I see that the compatible string is different for both IPs. For the 10/25G it is:

 

compatible = "xlnx,xxv-ethernet-3.1\0xlnx,xxv-ethernet-1.0";

For the 1/10/25G it is:

 

 

compatible = "xlnx,ethernet-1-10-25g-2.4";

On the AXI ethernet driver wiki I also couldn't find any mentioning of the 1/10/25G IP. Does this mean that there is no Linux support for it? Is there any other way to get a compatibility to 1G ethernet?
