Re: [libvirt] [PATCH 1/3] Tests for ACS in PCIe switches

New pciDeviceIsAssignable() function for checking whether a given PCI device can be assigned to a guest was added. Currently it only checks for ACS being enabled on all PCIe switches between root and the PCI device. In the future, it could be the right place to check whether a device is unbound or bound to a stub driver.
