Kein Link mit Intel 82599ES 10-Gigabit SFI/SFP+ Netzwerk Karte

Schönes Phänomen bei einer Intel 82599ES 10-Gigabit Karte mit SFP+ Adaptern, ein Interface läuft wie am Schnürchen, das andere bekommt um’s Verrecken den Link nicht hoch.

ethtool enp1s0f1 vermeldet folgendes:

Was einen nicht wirklich weiter bringt – das manuelle Setzen von Speed und Dupley mit ethtool geht auch nicht.

Schaut man etwas genau mit ethtool hin (Parameter -m) dann sieht die Ausgabe wie folgt aus:
