[PATCH RFC 0/2] virtio-pci: polling mode support
MSIX spec requires that device can be operated with all vectors masked, by polling. So the following patchset (lightly tested) adds this ability: when driver reads ISR, the device recalls a pending notification, and returns pending status in the ISR register. The polling driver can operate as follows: - map all VQs and config to the same vector - poll ISR to get status - this also flushes VQ
