2013-10-02dpa_offload: Allow statistics enable on NEXT_TABLE classifier table entriesMarian Chereji
The DPA classifier allowed the user to enable statistics only for "enqueue" and "drop" type table entries. It now allows the user to enable statistics also for the "next_table" type table entries.

2013-07-11dpa_offload: Switch DPA Classifier from using fmd/crc64 to using lib/crc64Marian Chereji
The DPA Classifier is computing a CRC64 ECMA by using the Frame Manager driver. Because the CRC64 ECMA generic module was recently accepted in linux/lib it will now use this CRC64 module instead of the implementation from FMan driver.

2013-07-11dpa_offload: Add protection against concurrent HM ops runtime modificationsMarian Chereji
When modifying a header manipulation operation at runtime, the DPA Classifier uses the FMD call FM_PCD_ManipNodeReplace. This function locks the entire PCD and will fail if the PCD is already locked (it is not a blocking function). The parallel access protection mechanism in DPA Classifier would only protect against parallel access ON THE SAME MANIP NODE. It used to ALLOW parallel access on DIFFERENT HM nodes, but this will fail due to the locking system in the FMD. This patch updates the locking mechanism in DPA Classifier for the HM runtime modification functions so that a single call to FM_PCD_ManipNodeReplace can happen at any one time.

For both Traffic Manager Class or Congestion Group the values returned can be the number of bytes or the number of frames dequeued from a Class Queue, respectively rejected in all Class Queues that belong to the Congestion Group.
