Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=008ca35f6e87be1d60b6af3d1ae247c6d5c2531d



--------------------------------

The 82599 PF driver disable VF driver after a special MDD event occurs.
Adds the option for administrators to control whether VFs are
automatically disabled after several MDD events.
The automatically disabling is now the default mode for 82599 PF driver,
as it is more reliable.

This addresses CVE-2021-33061.
