[c-nsp] channel fails when using sup 10g port ?

Yes I saw that feature, but I need the gig ports.

I did find a log entry stating there was a QOS mismatch between the channel ports.  Since I have the "no mls channel-consistency" command in the channel config , that would imply it is not working on the sup 10G ports.    I did see that all the sup ports are on the same ASIC, maybe that is stopping the consistency check from working.
