[f-nsp] Packet loss on MLXe-4

[Mike Tindle]

If you're sparing a -X with a vanilla non -X (or the other way around), be aware that the chassis reports them as two different cards and you have to blow away the port config for one before inserting the other.  We spare both types of 4x10g cards for this reason. 

Regards,
Mike
