It seems like making an ethernet bridge shouldn't be hard; off the top of my head, if we wanted to bridge eth1 to wlan1 it would be something like:

  brctl addbr br0
  brctl addif br0 eth1
  brctl addif br0 wlan1
  ip link set br0 up

or the equivalent with ovs-vsctl

I frequently use RPi as a programmable soft switch, plugging in four USB-ethernet dongles. On my Pi it splits the USB bandwidth, but it's still very useful.

I wondered too, and found this from the debian docs: https://wiki.debian.org/BridgeNetworkConnectionsProxyArp

TL;DR: Some routers don't like it, so layer 3 might work better
