My NetworkingDriverKit extension is failing on Monterey.

The RegisterEthernetInterface() call is returning a result of 0x08e4bd01.

This code works correctly on both Catalina and BigSur.

Can't find any information on that error code. Or what might have changed for Monterey.

Suggestions would be welcome!

Hello, sl149q

Have you solve this problem? Cause i have similar problem. The RegisterEthernetInterface() call is returning a result of 0x3dcbd500 in Monterey. This code works correctly on both Catalina and BigSur, too.

Any idea or suggestions would be welcome!!
