Here is what bypass mode does:

https://github.com/SpaceExplorationTechnologies/starlink-wifi-gen2/blob/main/openwrt/package/base-files/files/sbin/setup_iptables.sh#L19
https://github.com/SpaceExplorationTechnologies/starlink-wifi-gen2/blob/main/openwrt/package/base-files/files/sbin/wifi#L213
https://github.com/SpaceExplorationTechnologies/starlink-wifi-gen2/blob/main/openwrt/package/base-files/files/etc/init.d/wifi_control#L26 


So packages still going through this chain:
Dishy -> Mediatek PHY -> Linux kernel -> br-lan -> Linux kernel -> 
External LAN PHY (Marvell or MTK).

It's better to use a PoE injector and run tests without the Starlink router.
