In order for this to work on transmit, we need to add forward offloading
to the bridge so that we can, for example, send one FORWARD from the CPU
to send an ARP broadcast to swp1..4 instead of four FROM_CPUs.

Wouldn't this be solved if the CPU master interface was a bonding interface?

I don't see how you would do that. Would DSA keep returning -EPROBE_DEFER
until user space decides to set up a bond over the master interfaces?
How would you even describe that in device tree?
