       Device and vring operations.

       Definition at line 277 of file rte_vhost.h.

int(*new_device)(intvid)
       Add device.

       Definition at line 278 of file rte_vhost.h.

   void(*destroy_device)(intvid)
       Remove device.

       Definition at line 279 of file rte_vhost.h.

   int(*vring_state_changed)(intvid,uint16_tqueue_id,intenable)
       triggered when a vring is enabled or disabled

       Definition at line 281 of file rte_vhost.h.

   int(*features_changed)(intvid,uint64_tfeatures)
       Features could be changed after the feature negotiation. For example, VHOST_F_LOG_ALL will be set/cleared
       at the start/end of live migration, respectively. This callback is used to inform the application on such
       change.

       Definition at line 289 of file rte_vhost.h.

   void(*guest_notified)(intvid)
       This callback gets called each time a guest gets notified about waiting packets. This is the interrupt
       handling through the eventfd_write(callfd), which can be used for counting these 'slow' syscalls.

       Definition at line 300 of file rte_vhost.h.

   bool(*guest_notify)(intvid,uint16_tqueue_id)
       If this callback is registered, notification to the guest can be handled by the front-end calling
       rte_vhost_notify_guest(). If it's not handled, 'false' should be returned. This can be used to remove the
       'slow' eventfd_write() syscall from the datapath.
