Add initial support for the DSA driver for SoC-e FPGA-based (IP core)
Ethernet switches.
Let me start with a dumb question. Is this a true soft core switch,
which is synthesised and running in the FPGA? Or is it hardware at the
edge of the FPGA SoC?

If it is synthesised, do we have to deal with different synthesis
options? Are there registers which indicate what these options are?

Where as if it is fixed hardware in the SoC we don't need to worry so
much about variations, it is fixed at the SoC level.
There are different variants of the SoC-e switch IP, which can be
additionally configured at runtime with proprietary userspace software.
What sort of configuration?
