bluescreen

When using DPDK on windows server 2019 sometimes we get a bluescreen.

This bluescreen seams to be caused by virt2phys.sys

The issue has only been reproduced on Windows server 2019.

On windows 10,11 and server 2022 no bluescreen.

To reproduce this issue only test-pmd is necessary.

Bellow the crash analyse:
