As specified in 802.1Qau spec. Add this optional attribute to the DCB netlink layer. To allow for application to use the new attribute, NIC drivers should implement and register the callbacks ieee_getqcn, ieee_setqcn and ieee_getqcnstats. The QCN attribute holds a set of parameters for management, and a set of statistics to provide informative data on Congestion-Control defined by this spec.
