> 5/5 of our productive Freifunk mesh  rb912uag  nodes are able to provide 1G Ethernet with the old ar71xx but not with current ath79 trunk … force a Ethernet speed downgrade to just 100M (ethtool -s eth0 advertise 0x008) works for 4/5 … 1 node does not even work with this… there is a 30m CAT5 ethernet cable between the  rb912uag mesh router and the first openwrt xiaomi 4A AP (Gigabit version) .. working properly under ar71xx with 1G … with ath79 trunk 1G is not working and 100M is not working either… my guess is that the ethernet power for tx or rx or both is in ath79 different compared to ar71xx … so I would expect to find different register settings on ar71xx and ath79 for the ar8003 chip.. what do you think ? .. devmem2 read the register space from ar71xx und ath79 and compare ?

Regarding ethernet --> Should be fixed


Please give my staging tree a try for that.
