[dpdk-dev] [PATCH v4] examples/skeleton-cat: PQoS CAT and CDP, example of libpqos usage

This patch implements PQoS as an sample application. PQoS allows management of the CPUs last level cache, which can be useful for DPDK to ensure quality of service. The sample app links against the existing 01.org PQoS library (https://github.com/01org/intel-cmt-cat). Signed-off-by: Wojciech
