Miniport NCM driver

NTDEV

hi
I am developing Miniport NCM driver with usb protocol for Mobile broadband device.

While running HCK test (2machine -connectivity test), adapter is attached to the network properly when i get the network connection status from adapter.
After sometimes unbinding and binding is happening in the test, so NDIS calling pause and restart state to miniport driver .
In pause state , stopped the datapath. Restart state i restart the datapath. After restart network is not connected after sending Link status up to NDIS, but adapter is still connected with the network. So got below failure in HCK test
WaitforMediaConnect: OID_GEN_MEDIA_CONNECT_STATUS returned
WaitforMediaConnect: OID_GEN_MEDIA_CONNECT_STATUS returned
WaitforMediaConnect: OID_GEN_MEDIA_CONNECT_STATUS returned
up to 80 retries
My question is

  1. After restart state adapter is not sending network connection status. Is it correct or not?
  2. OID_GEN_MEDIA_CONNECT_STATUS oid is not called to miniport driver verified through logs?
  3. In pause state did not give any Link down status to NDIS. IS it correct?
