It seems that you have Yukon EC Ultra and 88E1149 PHY. Due to lack of
hardwares Yukon EC Ultra was not tested by me and it may have bugs.
It's also known that 88E1149 PHY has some issues which were not solved
yet. I have a WIP version that may fix Yukon EC Ultra issues but I'm
not sure whether it would work or not. Would you try attached patch?
