Guests could not call those functions directly, it is triggered by for
example writing to some of the registers like reset or others.

Since the kernel does not check the interleave capability, a
3-way, 6-way, 12-way or 16-way region can be create normally.
Applications can access the memory of 16-way region normally because
qemu can convert hpa to dpa correctly for the power of 2 interleave
ways, after kernel implementing the

If a virtio-net device has the VIRTIO_NET_F_MRG_RXBUF feature
but not the VIRTIO_RING_F_INDIRECT_DESC feature,
'VirtIONetQueue->rx_vq' will use the merge feature
to store data in multiple 'elems'.
The 'num_buffers' in the virtio header indicates how many elements are merged.

We already attempted to set and clear can_do_io before the first
and last insns, but only used the initial value of max_insns and
the call to translator_io_start to find those insns.
Now that we track insn_start in DisasContextBase, and now that
we have emit_before_op, we can wait until we have

Jørgen properly identified the problem, though calling set_can_do_io
