[dpdk-dev] [PATCH 0/2] Improve service stop support

[Gage Eads <gage.eads@intel.com>]

Existing service functions allow us to stop a service, but doing so doesn't
guarantee that the service has finished running on a service core. This
patch set introduces a function, rte_service_may_be_active(), to check
whether a stopped service is truly stopped.

This is needed for flows that modify a resource that the service is
using; for example when stopping an eventdev, any event adapters and/or
scheduler service need to be quiesced first.

This patch set also adds support for the event sw PMD's device stop flush
callback, which relies on this new mechanism to ensure that the
scheduler service is no longer active.

Gage Eads (2):
  service: add mechanism for quiescing a service
  event/sw: support device stop flush callback
