Very bad ethernet performance

Hi,

This is a known issue with DL-3xxx and DL-5xxx devices actually.
The built-in macOS Ethernet driver is very inefficient with those devices. We receive sporadic reports about this issue and never got Apple to analyse this issue unfortunately.

The issue is not visible with any other driver we tried on the platform or other platforms, including our own driver that we used to ship before Apple provided the inbox driver in macOS. Also, DL-6xxx devices are not affected.

We have bug #31218016 open with Apple about this, our internal reference is #25056. If you experience this issue, you could raise a bug with Apple too to increase its priority.
