Hy.
I have a Problem with th rj45 port eth2 ( farthest from sfp cage).
I had this problem with my clearfog pro before, so i think the Problem come from my kernel or dts.
Here my kernel config : http://pastebin.fr/124233
And here the dts :

I can ifup the port eth2 but no traffic or ping pass.
Thank you by advance for your Help.
