[dpdk-dev] [PATCH v3 5/9] example/qos_sched: add dynamic config of subport
Savinay Dharmappa
savinay.dharmappa at intel.com
Wed Sep 16 18:43:49 CEST 2020
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.
