Maintain the feature and status bits in the x-query-virtio-status
output and, as usual, add human-readable output only in HMP.
Applications may find it useful to compare features and status
information directly. An upper application, for example, could
use the QMP command x-query-virtio-status to retrieve vhost-user
net device features and the "ovs-vsctl list interface" command to
retrieve interface features (in number format) in order to verify
the correctness of the virtio negotiation between guest, QEMU,
and OVS-DPDK. The application could then compare the two features
directly, without the need for additional feature encoding.
