[NetAdapterCx][Client Driver]Can't see wake up packet(from the wireshark view) #23

In NetAdapterCx Client Driver, I can use magic packet or patter packet to wake my system. but from wireshak, I can't see magic packet in wireshark view when I send magic packet in link partner. you can see the following picture Image But If I use NDIS driver, It can show the magic packet.

I add the NetAdapterReportWakeReasonPacket in the EvtDeviceWakeFromSxTriggered function. you can see the following picture Image

I see NDIS driver has two steps, the first step is to indicate wake reason, the second step is to indicate the wake-up packet when NIC link up. But I see netadapterCx driver does not have the two steps. And I find that the EvtDeviceDisarmWakeFromSx Event happen before NIC link up. I know that NetAdapterReportWakeReasonPacket must place between EvtDeviceWakeFromSxTriggered and EvtDeviceDisarmWakeFromSx. So I think it can not place NetAdapterReportWakeReasonPacket after NIC link up.

So anybody can give me suggestion to how to realize this feature for NetAdapterCx Driver.
