This patch set introduces an ethdev-based abstraction layer for Quality of
Service (QoS) Traffic Manager, which includes: hierarchical scheduling, traffic
shaping, congestion management, packet marking. The goal is to provide a simple
generic API that is agnostic of the underlying HW, SW or mixed HW-SW
implementation.

Patch 1 builds on the mechanism introduced by rte_flow in DPDK and generalizes
it to make it available for other ethdev features/capabilities (such as the
traffic manager). The goal is to define a plugin-like mechanism to extend
the ethdev functionality in a modular way as opposed to the current monolithic
approach.

Patch 2 introduces the generic ethdev API for traffic manager using the
above plugin-like mechanism for ethdev.

  ethdev: add capability control API
  ethdev: add hierarchical scheduler API
