Hi All,
I'm implementing VM migration support for open-VPP, an open source Vector 
Packet Processing (VPP) technology (https://wiki.fd.io/view/VPP) - A Linux 
foundation project. In lieu of it, I have hit an issue and I need some 
clarification.

In Qemu's vhost-user implementation, each queue is treated as a vhost-net 
device and during migration, vhost_user_set_log_base is invoked per device 
(queue). However, there is no information about the queue index in the API. How 
should the slave determine which queue the master is referring to ?

For example: If I have configured my guest with 4 queues, 
VHOST_USER_SET_LOG_BASE is invoked 4 times with different SHMFDs. How to map 
SHMFD to queue ID ?
