The patch reworks the generic flow API (rte_flow) implementation.
It introduces an abstract layer which provides a unified interface
for low-level filter engine (switch, fdir, hash) to register supported
patterns and actions and implement flow validate/create/destroy/flush/
query activities.
The patch also removes the existing switch filter implementation to
avoid compile error. Switch filter implementation for the new framework
will be added in the following patch.
