I would actually say, that is the core of your problem.

Look around at the networking world. Nobody uses x86 for core
networking. Nobody uses ACPI. Everything is MIPS, ARM, or Risc-V and
using DT.  Linux has mature and complex DT bindings for networking,
ACPI has nothing.

You might want to consider using DT with x86. It is possible. Take a
look at drivers/misc/lan966x_pci.dtso, which is used for networking,
and can be used on x86.
