Yes, my answer was that no IOCTL is currently provided to retrieve the
driver version. Consider that packet.dll version is strictly related to the
NPF version, since the driver and the dll are always installed toghether by
the winpcap installer, so if you don't install the WinPcap binaries manually
(a practice that we strongly discourage) the versions are granted to be
aligned.
In every case, different versions normally are not able to work together.
