What is the PacketsDroppedByDriver count? All the packets that has been dropped because not matching the filter or actual drop???

My PacketsDroppedByInterface is always 0, which is good but the PacketsDroppedByDriver is always high on any capture.

The interface is the physical device that captures the packets.

WinPcap driver reads the packets from the interface and sends them to your application.

As far as I know, the WinPcap driver has a buffer to hold packets that are waiting to be sent and the number of packets dropped by the driver is the number of packets that were dropped because lack of space in the buffer in addition to the number of packets dropped using the BPF.
