linux-generic: classification initial implementation
The following features are implemented in this classification implementation:
* Attaches PMR, PMR_SET to a Pktio entry
* Adds classifier object to pktio entry
* Attaches CoS values for L2 and L3 QoS to a Pktio entry
* Selects ClassOfService for a packet based on PMR, L2 QoS and L3 QoS values
* Selects a default CoS if packet does not match any of the assigned rules
* Selects an Error CoS for an Error packet
* Enqueues the packet to the queue associated with the selected CoS
