Thanks for providing the dependency list. Unfortunately they did not apply without error on my local tree, but this is caused by other patches I track. I managed to fix the conflicts, I think. Eventually I was able to get a PCIe M.2 ethernet interface working on my TQMa8MPxL based board. iperf showed >900MBit/s Tx and > 700 MBit/s Rx. Thanks for your effort. Once the depenencies and reviews are settled, you'll get my tested-by.
