I think this is it. It kinda makes sense. Even the config in the DTS, eth1 being minimal vs eth0 and eth2 being more config - speed, duplex, poll required, etc.
Open WRT then takes information coming/going to/from wan1/lan1-8/wan2 aka eth0/eth1/eth2 aka gmac0/gmac1/gmac2 respectively after applying firewall rules, then patches them together allowing the data transfer between them.

- This indicates a high security model, which would fit for a SMB router.
- It also provides physical/visual separation of our concerns (wan1, wan2, and lan) for security purposes.

upstream only has "gmac" but our highly specialized configuration requires 3 gmac.
I suggest we delete any upstream nodes ("gmac") , and define our own in the SOC block just as the manufacturer has for gmac0 gmac1 and gmac2.
As for switches, we defined them, but dont connect - init scripts connect them to gmac1

going to sleep. think and resume tomorrow.
