I don't think that's guaranteed. I needed to crimp a gigabit/fully-crossed crossover cable (https://en.wikipedia.org/wiki/Ethernet_crossover_cable#Fully_crossed) just the other day for direct use between an apu2 and an older MacBook. While I certainly hadn't needed one in the preceding 15+ years, not every two gigabit interfaces will link up every time, across every OS.
That being said, I would imagine no media would be detected if that were the issue here.
