Gluon: Ubiquiti Unifi AC Lite: Problems with eth0 persist

[smoe]

We found an issue with the 0.6.2 release concerning the AC Lite that was already mentioned on https://github.com/freifunk-gluon/gluon/issues/689 : the wlan works fine, but the ethernet connection fails. Eth0 is seen by the tools and IP number can be assigned, however tcpdump indicated no traffic on the connection at all. In contrast, the latest Lede-image is running flawlessly.
Could that driver of Lede possibly be backported?

Best regards,

Zafer and Steffen

what is the "0.6.2" release?
we need to know which exact gluon version you or your community are using.

I had some problems in the past with the AR803x PHYs. There are patches in LEDE which work around them. For example https://git.lede-project.org/?p=source.git;a=blob;f=target/linux/generic/patches-3.18/735-net-phy-at803x-fix-at8033-sgmii-mode.patch;h=4a8f532aa36f729339e01ebadd6ea3cb292d7ac9;hb=HEAD

There are also other RFCs which I've submitted in the past related to SGMII with this PHY (but with QCA955x as SoC) like https://patchwork.ozlabs.org/patch/606468/ (and other changes in this series). But these aren't in LEDE and thus I would expect to LEDE to be still affected.

EDIT: just gave sunbox a build for testing which only added the sgmii-mode workaround https://github.com/FreifunkVogtland/gluon/commit/2bd328cd0298c31e9ead4e54922da4f49c35eb14

The fix was applied to my router by @ecsv (http://vogtland.freifunk.net/map/#!v:m;n:802aa848b87c)

Uplink seems to be stable by now and the Config-Mode works also using DHCP.

Heya @NeoRaider,
These changes appear not made it to the 0.6.2.2 release tag while @Garunda's experimeal build just works smoothly. Since it is not so straight forward to reflash the device without Ethernet access, please kindly consider to forward those Ubiquity AC Lite changes to the next release.
Cheers,
Steffen

@smoe, the changes are in v2016.2.x; make sure you always make update and make clean after pulling.
