[dpdk-dev] [PATCH 09/13] examples/eventdev: add all type queue option
Pavan Nikhilesh
pbhagavatula at caviumnetworks.com
Thu Dec 7 21:37:01 CET 2017
Added configurable option to make queue type as all type queues i.e.
RTE_EVENT_QUEUE_CFG_ALL_TYPES based on event dev capability
RTE_EVENT_DEV_CAP_QUEUE_ALL_TYPES.
This can be enabled by supplying '-a' as a cmdline argument.
