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.
