This fixes incorrect supported link modes indicated when using ethtool on the Ubiquiti UniFi AC lite / LR / Mesh. eroot@OpenWrt:~# ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 100baseT/Half 100baseT/Full 1000baseT/Full 1000baseX/Full The reason for this is, that since kernel 5.4 the PHY capabilities are read dynamically from the PHY. As Ubiquiti leaves the PHY in a wrong state, the capabilities of the SGMII side of the PHY are read. As a side effect, 10 Mbit/s link modes did not work on these boards.

Add back explicit PHY feature flags for the AR8031 and
|
|
AR8033 PHY instead of reading them from the PHY.
|
|
|
|
The Botloader for Ubiquiti UniFi AC boards (and possibly more)
|
|
leave fiber page selected, thus we will end up reading the PHY
|
|
capabilities of the SGMII side (which does not offer 10 Mbit/s).
|
|
|
|
We already have a hack in place, which switches back to the copper
|
|
page, however this happens after capabilities are read.
|
|
|
|
The original conversation about 735-net-phy-at803x-fix-at8033-sgmii-mode
|
|
back in 2015 explicitly mention the UniFi AC Lite. The issue however is
|
|
not missing autonegotiation on the Fiber side, but the fact the PHY
|
|
is never switched to the copper side. So half of this patch is superfluous.
|
|
|
|
A fix is currently being upstreamed. Once this is mainlined and available to us,
|
|
these patches can be dropped:
|
|
|
|
735-net-phy-at803x-fix-at8033-sgmii-mode.patch
|
|
736-net-phy-at803x-add-at8031-features.patch
|
|
|
|
This was tested on a UniFi AC Lite.
