Since the topic is raised in multicast address list patchset, I'd like
to highlight it here as well. Current version uses failsafe ops directly
on sync to synchronize queues state which iterates over all sub-devices.
For already in sync sub-devices it does not go to driver since ethdev
functions checks current state and do nothing if it is already OK.
In theory it is possible to limit it to inactive devices and use
ethdev API instead of direct ops, but it requires a bit more lines of
code.

v2:
    - fix ops ordering
    - update testpmd documentation
    - add Gaëtan's acks

Ian Dolzhansky (4):
  app/testpmd: add queue deferred start switch
  net/failsafe: add checks for deferred queue setup
  net/failsafe: add Rx queue start and stop functions
  net/failsafe: add Tx queue start and stop functions
