Steps to reproduce

• flash an affected build and power up device
• no special settings necessary
• LEDs of '2.5G / PoE' port will start flash, even without connected cable

Actual behaviour

both LEDs (amber + green) on the '2.5G / PoE' port of the OpenWrt One are constantly flashing regardless of connection.

Terms

• I am reporting an issue for OpenWrt, not an unsupported fork.

Start by comparing commit 7d620f83e39e189edf25a37ef70e6abb83a35115 on the openwrt-24.10 branch for the mediatek/filogic OpenWrt One target. Reproduce with an affected self-built image, with and without a cable, and compare the 2.5G / PoE port with the unaffected 1G port. Done means amber indicates link-up and green blinks only during transmission.
