Now the only thing missing is "Fixes" tag, which references commit which introduced the issue. Probably this will be the commit which added ethernet node. This tag is important for deciding which commits should be backported to stable releases. Take a look in v1 for M2U fixes tag. Btw, each version should have changelog under "---" line, so maintainers and reviewers know what changed. Best regards, Jernej

"Fix ethernet phy-mode" reads much better than "Fix ethernet node", which could mean a number of things. ChenYu

BPi Pro needs TX and RX delay for Gbit to work reliable and avoid high packet loss rates. The realtek phy driver overrides the settings of the pull ups for the delays, so fix this for Banana Pro.
