Hello,
I am trying to attach a second ethernet port to a Raspberry Pi 4 using a WIZ550io module, however the OS does not seem to be able to find the driver for it. The Raspberry Pi OS has wiznet drivers built into the kernel by default, which do show up as being loading when running lsmod, but it fails to create a new ethernet connection. After reviewing the source code for the drivers, I have found that the drivers are rather old (~2012). Is this driver compatible with the WIZ550io? Is this driver compatible with the Raspberry Pi 4? Are there any newer drivers available? Does the ioLibrary contain a linux kernel driver? Or can it be built into a kernel driver?
