Which is the area where the sample lives?
/network/ndis/
Describe the issue
The MUX driver does not run well over time alongside a Hyper-V virtual switch . Packet drop and stalling is appearing after a few hours. Sugets changing NDIS version (at least 6.30) , and adding neccessary handling API calls for new version.
