#22135 new defect

Unifi AP AC LR No ethernet on trunk [and solution]

Reported by: anonymous Owned by: developers
Priority: normal Milestone:
Component: kernel Version: Trunk
Keywords: mii ag71xx ubiquiti unifiac Cc: blogic


The unifiac port targets this device, but flashing that image will require a serial console to access. The root issue is that the mii_bus part of the ag71xx_platform_data is not populated by dev_eth.c.

The symptoms of the bug:
[ 0.680522] libphy: ag71xx_mdio: probed
[ 0.684622] ag71xx ag71xx.0: no MII bus device specified
[ 0.690117] ag71xx: probe of ag71xx.0 failed with error -22

After dirty patch below:

[ 0.663845] libphy: ag71xx_mdio: probed
[ 1.335853] ag71xx ag71xx.0: connected to PHY at ag71xx-mdio.0:04 [uid=004dd074, driver=Atheros 8031/8033 ethernet]
[ 1.347180] eth0: Atheros AG71xx at 0xb9000000, irq 4, mode:SGMII

The attached patch fixes it, but obviously breaks everything else, so a more openwrt specific fix could be derived from it.

I can confirm this issue.

This should already be resolved in r49277.
I have some users which already reported back, that LR
worked fine with trunk.

You are right. I did not expect that it was configured as a router on the only ehternet port. After I was unable to find the device on my network I thought this issue applies.
Will add a note on the wiki.
