IPv6 CoS (BA, MF classification & rewrite, scheduling based on TC)

This features introduces BA classifiers, Multifield classification and rewrite, and scheduling based on traffic classes for IPv6 traffic. BA classifiers allow you to set the forwarding class and loss priority of a packet based on the Differentiated Services code point (DSCP) value, IP precedence value, and IEEE 802.1p value. Multifield classifiers allow you to set the forwarding class and loss priority of a packet based on firewall filter rules after multiple fields in a packet such as source and destination addresses and source and destination port numbers are checked. Traffic classes allow you to create congestion notification profiles.
