To fulfil this demand\nit is proposed to extend indirect action sharing across the\nmultiple ports. This kind of sharing would be extremely useful\nfor the meters and counters, allowing to manage the single\nconnection over the multiple ports.\n\nThis cross-port object sharing is hard to implement in\ngeneric way merely with software on the upper layers, but\ncan be provided by the driver over the single hardware\ninstance, where multiple ports reside on the same physical\nNIC and share the same hardware context.\n\nTo allow this action sharing application should specify\nthe \"host port\" during flow configuring to claim the intention\nto share the indirect actions. All indirect actions reside within\n\"host port\" context and can be shared in flows being installed\non the host port and on all the ports referencing this one.\n\nIf sharing between host and port being configured is not supported\nthe configuration should be rejected with error. There might be\nmultiple independent (mutual exclusive) sharing domains with\ndedicated host and referencing ports.\n\nTo manage the shared indirect action any port from sharing domain\ncan be specified. To share or not the created action is up to\napplication, no API change is needed.\n\nSigned-off-by: Viacheslav Ovsiienko <viacheslavo@nvidia.com>\n\nViacheslav Ovsiienko (3):\n ethdev: sharing indirect actions between ports\n app/testpmd: add host port parameter into flow config\n app/testpmd: add shared indirect action support\n\n app/test-pmd/cmdline_flow.c | 63 ++++++++++++++++++++-\n doc/guides/rel_notes/release_23_03.rst | 6 ++\n doc/guides/testpmd_app_ug/testpmd_funcs.rst | 4 +-\n lib/ethdev/rte_flow.c | 6 ++\n lib/ethdev/rte_flow.h | 11 ++++\n 5 files changed, 88 insertions(+), 2 deletions(-)" }
