[dpdk-dev] [PATCH v2 06/10] example/qos_sched: add dynamic config of subport

[Savinay Dharmappa <savinay.dharmappa@intel.com>]

Modify the qos_sched application to build the hierarchical scheduler
with default subport bandwidth profile. It also allows to configure
a subport with different subport bandwidth profile dynamically.
