In SW assisted live migration, vDPA driver will stop all virtqueues
and setup up SW vrings to relay the communication between the
virtio driver and the vDPA device using an event driven relay thread
This will allow vDPA driver to help on guest dirty page logging for
live mi

The used/avail queue indexes are not bound by queue
size, because HW calculates descriptor entry index by
performing a simple modulo between queue index and queue_size.
So, do not check initial used and avail queue indexes

Increase the number to default RX/TX queue pairs to 8,
and add MQ feature flag to vDPA protocol features.

libvhost calls dev_conf() before prosessing the
VHOST_USER_SET_VRING_CALL message for the last VQ. So
this message is processed after dev_conf() returns.
However, the dev_conf() function spawns a thread to set

When DPDK app is running in the VF, it sometimes rings the doorbell
before dev_config has had a chance to complete and hence it misses
the event. As workaround, ring the doorbell when vDPA reports the
notify_area to QEMU.

support multiple VF(s) and rte_memzone_reserve_aligned expects unique
