Ethernet Only Negotiates at 10BaseT on Archer C7 V2 on OpenWrt Chaos Calmer 15.05-rc3

Component: packages Version: Trunk

Under 15.05-rc3 on the Archer C7 V2, I am unable to negotiate anything other than a 10BaseT ethernet connection. Even when attempting to force the negotiation higher from the connected computer.

Works fine for me out of the box. CC 15.05 rc3 on Archer C7 v2. I get
1000/Full to a PC and 100/Full to a raspberry pi (the max it can do).
No special settings, no need to force speeds.

Usually, forcing the speed/duplex is the wrong thing to do and is papering over
some other problem.

Check your cabling?

Same problem here running stable

CHAOS CALMER (15.05, r46767)

On the WAN side i can only negotiate 10BaseT, which limits my download-stream to one third.
How can i workaround this? Unfortunately it's not the cabling (CAT6, 7.5m). ;-)

Sorry for bothering you, but i swear i had the same problem for sometime.
I rechecked Archer C7 to give more output, but found everything back at normal.
