[dpdk-dev] [PATCH 0/2] net/softnic: add flow classification support

This patchset extends the softnic device by implementing
the software fallback for flow classification as defined
using Flow APIs. When feature is enabled, softnic classifies
and executes actions on the received packets based on flow
rules specified using rte_flow.h.

The motivation behind this feature is to implement metering
and policing function in softnic which requires each flow to
be classified at the preceding stage of the packet processing
pipeline. Another aspect is to  support classification of the
greater number of flows (For e.g. 64K) which is not feasible
in some hardware due to resource limitation such as memory, etc.

This feature, inherently, uses the abstraction provided by dpdk
librte_table library to create hash table for classification,
and allows users to validate, add and delete flow rules. Current
version does not implement all functions and will be completed
in the next version.
