Revert: "vfio-pci: Mask INTx if a device is not capabable of enabling it"
This reverts commit 2170dd04316e0754cbbfa4892a25aead39d225f7 The intent of commit 2170dd04316e ("vfio-pci: Mask INTx if a device is not capabable of enabling it") was to disallow the user from seeing that the device supports INTx if the platform is incapable of enabling it. The detection of this case however incorrectly includes devices which natively do not support INTx, such as SR-IOV VFs, and further discussions reveal gaps even for the target use case. Reported-by: Arjun Vynipadath <arjun@chelsio.com> Fixes: 2170dd04316e ("vfio-pci: Mask INTx if a device is not capabable of enabling it") Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
