These patches introduced the support for configure interrupt 

These codes are tested on x86_64 and aarch64 platforms.  
the test scenario is based on vp-vdpa/vdpa_sim /virtio net device, with
the irqfd and without irqfd.

Tested in virtio-pci bus and virtio-mmio bus


Change in v2:
Add support for virtio-mmio bus
active the notifier while the backend support configure interrupt
misc fixes from v1

Change in v3
fix the coding style problems

Change in v4
misc fixes from v3
merge the set_config_notifier to set_guest_notifier
when vdpa start, check the feature by VIRTIO_NET_F_STATUS

Change in v5
misc fixes from v4
split the code to introduce configure interrupt type and the callback function
will init the configure interrupt in all virtio-pci and virtio-mmio bus, but will
only active while using vhost-vdpa driver

Change in v6
misc fixes from v5
decouple vq from interrupt setting and misc process
fix the bug in virtio_net_handle_rx

Change in v7
misc fixes from v6
decouple vq from interrupt setting and misc process
decouple vq from vector use/release process
decouple vq from set notifier fd handler process
move config_notifier and masked_config_notifier to VirtIODevice
fix the bug in virtio_net_handle_rx, add more information
add VIRTIO_CONFIG_IRQ_IDX as the queue number for configure interrupt 

Change in v8
misc fixes from v7
decouple vq from interrupt setting and misc process
decouple vq from vector use/release process
decouple vq from set notifier fd handler process
move the vhost configure interrupt to vhost_net

Change in v9
misc fixes from v8
address the comments from v8

Change in v10
fix the hang issue in qtest
address the comments from v9

Change in v11
fix the crash in aarch64 plateform.
fix the crash upstream reported

Change in v12
fix the typo and add the comments

The email threading of this series isn't setup right. Each
patch is appearing as a new top level mail, rather than as
a reply to the cover letter.

I can encourage using 'git-publish' to send patch series to
qemu-devel to avoid this kind of mistake, as well as giving
tracking of each version you send through local git tags,
and being able to auto-remember the cover letter contents.


With regards,
Daniel

sure, Thanks Daniel, I will send these patches by git-pbulish

Thanks
