Hi, Michael
We can implement the test by modifying qemu; 1. force the
VIRTIO_F_RING_PACKED feature bit to be set, 2. set
VIRTIO_NET_RX_QUEUE_DEFAULT_SIZE and VIRTIO_NET_TX_QUEUE_DEFAULT_SIZE to
the value of non power_of_2, 3. remove the check of is_power_of
virtqueue, then qemu can create the required virtual device (non power_2
size , packed virtqueue device) ;In this way, any length and packed ring
test can be performed;
remove the modified code, I can test split vq, and can see...

[PATCH v4 0/3] virtio_net: allow hypervisor to indicate linkspeed and duplex setting
We have found it useful to be able to set the linkspeed and duplex
settings from the host-side for virtio_net. This obviates the need
for guest changes and settings for these fields, and does not require
custom ethtool commands for virtio_net.
The ability to set linkspeed and duplex is useful in various cases
as described here:
