[dpdk-dev] [PATCH 08/15] sched: update grinder functions for config flexibility

Jasvinder Singh jasvinder.singh at intel.com
Fri Aug 23 16:45:55 CEST 2019


Modify packet grinder functions of the schedule to allow different
subports of the same port to have different configuration in terms
of number of pipes, pipe queue sizes, etc.
