Re: [libvirt] [PATCH] Force FLR on for buggy SR-IOV devices.

Some buggy PCI devices actually support FLR, but forget to advertise that fact in their PCI config space. However, Virtual Functions on SR-IOV devices are *required* to support FLR by the spec, so force has_flr on if this is a virtual function.
