2b9c78543663 Reverted default branch to stable-1.5. Florian Pose <fp@igh-essen.com> parents: diff changeset	2269	* advertised none, we will configure ourselves to
2b9c78543663 Reverted default branch to stable-1.5. Florian Pose <fp@igh-essen.com> parents: diff changeset	2270	* enable Rx Flow Control only. We can do this safely

2b9c78543663 Reverted default branch to stable-1.5. Florian Pose <fp@igh-essen.com> parents: diff changeset	2273	* no harm done since we won't be receiving any PAUSE
2b9c78543663 Reverted default branch to stable-1.5. Florian Pose <fp@igh-essen.com> parents: diff changeset	2274	* frames anyway. If the intent on the link partner was
