Hi Avi Marcelo
This patchset would add emulation of MSI-X mask bit for assigned devices in
QEmu.
BTW: We are also purposed an acceleration of MSI-X mask bit for KVM - to get
it done in kernel. That's because sometime MSI-X mask bit was accessed very
frequently by guest and emulation in QEmu
This patch enable per-vector mask for assigned devices using MSI-X.
