I've just checked my logs and I can confirm that it was atphy(4) even in = stable/8. Sep 26 15:55:19 nas kernel: atphy0: <Atheros F1 10/100/1000 PHY> PHY 0 = on miibus0 Sep 26 15:55:19 nas kernel: atphy0: none, 10baseT, 10baseT-FDX, = 100baseTX, 100baseTX-FDX, 1000baseT-FDX, 1000baseT-FDX-master, auto I'll post more info when I try again stable/8 on this hardware.
