The QEMU project is currently moving its bug tracking to another system.
For this we need to know which bugs are still valid and which could be
closed already. Thus we are setting older bugs to "Incomplete" now.
If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.
Thank you and sorry for the inconvenience.

Title:
virtio only support packed ring size power of 2
Status in QEMU:
Incomplete
Bug description:
Issue discription：
When QEMU starts with "-device
virtio-net-pci,netdev=netdev0,mac=52:54:00:00:00:01,disable-modern=false,mrg_rxbuf=on,rx_queue_size=1025,tx_queue_size=1025,mq=on,vectors=15,packed=on"
It raises error: Invalid rx_queue_size (= 1025), must be a power of 2
between 256 and 1024
Analysis:
According to virtio1.1 spec, the packed queue size value does not have to be
a power of 2.
