Pixhawk 6X ETH not working under 1.13.3

I find Pixhawk 6X ETH not working under 1.13.3,but under 1.14.0 it works,I need to complete some development under version 1.13, so I would like to ask which areas have been upgraded from version 1.13 to 1.14

You can read the release notes for 1.13 and 1.14 on our docs, here’s a link that can get you to both Releases | PX4 Guide (main)

Regarding ETH, maybe you want to describe the issue? perhaps there’s someone that can help you.

Thank you for your reply!Pixhawk 6X can start netman,but I can’t connect to the PX4 through “ping”, there is no reply. I use the same firmware to run on V5X,It can work. Interestingly PX4 6X works normally in firmware version 1.14, perhaps some issues have been fixed,but I can’t find them in the release notes. Can you provide more details?
