ovs-ofctl queue-stats not show queues after adding link bandwidth on mininet

[joe820912boy]

The problem is that after adding the link bandwidth on mininet, like that,
net.addLink(s1,s2,1,1,cls=TCLink,bw=1000)
that I tried to check queue-stats but there was not queue on switch port,
but ovs-vsctl list qos and ovs-vsctl list queue these two commands still worked

If I delete the bandwidth on mininet, like that,
net.addLink(s1,s2,1,1)
that ovs-ofctl queue-stats is working again

I tried google this problem on mininet-discuss but seem to be no answer on it,
was there someone facing this problem before?

I found that this problem post about adding delay on link configuration,
but it seemed that this problem also on link bandwidth setup

mininet/mininet#132

I found this pull

I followed this instruction, adding the code on node.py in mininet, and re-installed again,
but the problem still occurred.

Did someone use this instruction and solve the problem before?
plz let me know, ths
