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! networkInit_Impl [result = RegisterEthernetInterface(ivars->fHostMAC, ivars->poolPacketBuffer, ivars->queues, 4)] Unkown_kIOReturn 8e4bd01
