First of all my 10 Gigabit connection is still working. Over the last year I used varying linux kernels between 3.18 and 4.0. But in terms of features those kernels are over 2 years old. Therefore this post deals with the issues from last time concerning kernel releases 4.1 and greater.
Finally I got my 10 Gigabit connection working. It took many hours scattered over two months. From the uncertainty that the used hardware may have a bug, over driver to linux kernel issues. But all in all is a 10 GBit home network worth it?
