40G/50G Ethernet Subsystem Petalinux driver

The Linux AXI Ethernet driver appears to only support up to the 10G/25G Ethernet Subsystem, and I don't see Linux driver support available at all for the 40G/50G subsystem. Is there a reasonable way to make this work in Petalinux on a Microblaze? As far as I understand it should be relatively transparent since the register/MAC interface is nearly identical and the data tx/rx is done via AXI DMA. As it is, I don't see the Ethernet subsystem being detected at all during Petalinux configuration or after booting, despite it appearing correctly in the device tree configuration.
