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".

I'm not sure I fully understand what your question is though, so I may
not have answered it.
