[dpdk-dev] [PATCH v5 6/9] example/ip_pipeline: add dynamic config of subport

Savinay Dharmappa savinay.dharmappa at intel.com
Wed Sep 30 21:24:31 CEST 2020


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