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 app/test-pmd/cmdline.c | 91 +++++++++++ doc/guides/nics/features/failsafe.ini | 1 + doc/guides/rel_notes/release_18_11.rst | 15 ++ doc/guides/testpmd_app_ug/testpmd_funcs.rst | 7 + drivers/net/failsafe/failsafe_ether.c | 88 +++++++++++ drivers/net/failsafe/failsafe_ops.c | 167 +++++++++++++++++++- 6 files changed, 368 insertions(+), 1 deletion(-)
