It looks like the driver also depends on the microchip PHY which we will also need to backport as this didn't exist in RHEL7's 3.10 kernel.

Hi Phil,
thanks a lot for that quick service!
These are my observations:
- module microchip gets loaded when lan78xx does. In fact it can get unloaded again without effecting the lan78xx driver. So I can blacklist the microchip module for not getting loaded from the beginning.
- in principle the Ethernet gets configured properly as it seems
- However, once the RJ-45 Ethernet cable is getting connected, the kernel drops a warning as shown below. The messages is not dependent whether the microchip module is loaded or not. So it appears in either case.
Maybe the slowpath warning results on the fact that el7's 3.10 kernel has some backports implemented which the vanilla 3.10 kernel doesn't?
This is what journalctl tells me:
