In this commit, virtqueue operations including: set_vq_num(), set_vq_address(), set_vq_ready() and get_vq_ready() access PCI registers directly to take immediate actions.

v2 for internal review - heavily reworked NET_F_MAC patch, matches recent PR-68875 - reordered to put "clean and reset vqs" before "alloc-irq" to make them slightly simpler patches - other minor cleanups for simpler patches These are some fixes for device providing a MAC address, for allocating irq resources later to support vhost use, and for properly cleaning vq info

Formerly, ifcvf driver has implemented a lazy-initialization mechanism for the virtqueues and other config space contents, it would store all configurations that passed down from the userspace, then load them to the device config space upon DRIVER_OK. This can not serve live migration, so this series implement an immediate initialization mechanism, which means rather than the former store-load

Hi, These patches try to support multi virtual queues(multi-vq) in one virtio-blk device, and maps each virtual queue(vq) to blk-mq's hardware queue. With this approach, both scalability and performance on virtio-blk device can get improved. For verifying the improvement, I implements virtio-blk multi-vq over qemu's dataplane feature, and both handling host notification from each vq and

This commit synchronize irqs of the virtqueues and config space in the reset routine. Thus ifcvf_stop_hw() and reset() are refactored as well.
