Is there any change of these ethernet ports being used to connect to
an Ethernet switch. We have had issues in the past with these sort of
platform devices combined with DSA.

There are only two possibilities.  The BGX MACs have a multiplexer that
allows them to be connected to either the "octeon_mgmt" MIX packet
processor, or to the "ethernet-mac-pki" PKI/PKO packet processor.  The SoCs
supported by these drivers do not contain any hardware that would be
considered an "Ethernet switch".

Hi David

I was thinking of an external Ethernet switch. You generally connect
via RGMII to a port of the switch.
