From: Adrien Mazarguil Date: Wed, 25 Apr 2018 15:28:08 +0000 (+0200) Subject: ethdev: add physical port action to flow API X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=e7b657058fc1f7fba33ae7c5dfab6102d5abfeb7;p=dpdk.git ethdev: add physical port action to flow API This patch adds the missing action counterpart to the PHY_PORT pattern item, that is, the ability to directly inject matching traffic into a physical port of the underlying device. It breaks ABI compatibility for the following public functions: - rte_flow_copy() - rte_flow_create() - rte_flow_query() - rte_flow_validate() Signed-off-by: Adrien Mazarguil Acked-by: Andrew Rybchenko Acked-by: Mohammad Abdul Awal --- diff --git a/app/test-pmd/cmdline_flow.c b/app/test-pmd/cmdline_flow.c index f9f9372772..3567148015 100644 --- a/app/test-pmd/cmdline_flow.c +++ b/app/test-pmd/cmdline_flow.c @@ -182,6 +182,9 @@ enum index { ACTION_VF, ACTION_VF_ORIGINAL, ACTION_VF_ID, + ACTION_PHY_PORT, + ACTION_PHY_PORT_ORIGINAL, + ACTION_PHY_PORT_INDEX, ACTION_METER, ACTION_METER_ID, }; @@ -623,6 +626,7 @@ static const enum index next_action[] = { ACTION_RSS, ACTION_PF, ACTION_VF, + ACTION_PHY_PORT, ACTION_METER, ZERO, }; @@ -657,6 +661,13 @@ static const enum index action_vf[] = { ZERO, }; +static const enum index action_phy_port[] = { + ACTION_PHY_PORT_ORIGINAL, + ACTION_PHY_PORT_INDEX, + ACTION_NEXT, + ZERO, +}; + static const enum index action_meter[] = { ACTION_METER_ID, ACTION_NEXT, @@ -1714,6 +1725,30 @@ static const struct token token_list[] = { .args = ARGS(ARGS_ENTRY(struct rte_flow_action_vf, id)), .call = parse_vc_conf, }, + [ACTION_PHY_PORT] = { + .name = "phy_port", + .help = "direct packets to physical port index", + .priv = PRIV_ACTION(PHY_PORT, + sizeof(struct rte_flow_action_phy_port)), + .next = NEXT(action_phy_port), + .call = parse_vc, + }, + [ACTION_PHY_PORT_ORIGINAL] = { + .name = "original", + .help = "use original port index if possible", + .next = NEXT(action_phy_port, NEXT_ENTRY(BOOLEAN)), + .args = ARGS(ARGS_ENTRY_BF(struct rte_flow_action_phy_port, + original, 1)), + .call = parse_vc_conf, + }, + [ACTION_PHY_PORT_INDEX] = { + .name = "index", + .help = "physical port index", + .next = NEXT(action_phy_port, NEXT_ENTRY(UNSIGNED)), + .args = ARGS(ARGS_ENTRY(struct rte_flow_action_phy_port, + index)), + .call = parse_vc_conf, + }, [ACTION_METER] = { .name = "meter", .help = "meter the directed packets at given id", diff --git a/app/test-pmd/config.c b/app/test-pmd/config.c index 272e25f2cc..7a954c5143 100644 --- a/app/test-pmd/config.c +++ b/app/test-pmd/config.c @@ -1091,6 +1091,7 @@ static const struct { MK_FLOW_ACTION(RSS, sizeof(struct rte_flow_action_rss)), MK_FLOW_ACTION(PF, 0), MK_FLOW_ACTION(VF, sizeof(struct rte_flow_action_vf)), + MK_FLOW_ACTION(PHY_PORT, sizeof(struct rte_flow_action_phy_port)), MK_FLOW_ACTION(METER, sizeof(struct rte_flow_action_meter)), }; diff --git a/doc/guides/prog_guide/rte_flow.rst b/doc/guides/prog_guide/rte_flow.rst index 4e053c24b3..a39c1e1b00 100644 --- a/doc/guides/prog_guide/rte_flow.rst +++ b/doc/guides/prog_guide/rte_flow.rst @@ -1433,6 +1433,26 @@ See `Item: VF`_. | ``id`` | VF ID | +--------------+--------------------------------+ +Action: ``PHY_PORT`` +^^^^^^^^^^^^^^^^^^^^ + +Directs matching traffic to a given physical port index of the underlying +device. + +See `Item: PHY_PORT`_. + +.. _table_rte_flow_action_phy_port: + +.. table:: PHY_PORT + + +--------------+-------------------------------------+ + | Field | Value | + +==============+=====================================+ + | ``original`` | use original port index if possible | + +--------------+-------------------------------------+ + | ``index`` | physical port index | + +--------------+-------------------------------------+ + Action: ``METER`` ^^^^^^^^^^^^^^^^^ diff --git a/doc/guides/rel_notes/release_18_05.rst b/doc/guides/rel_notes/release_18_05.rst index 2a325ba6e5..1308b8e3ac 100644 --- a/doc/guides/rel_notes/release_18_05.rst +++ b/doc/guides/rel_notes/release_18_05.rst @@ -288,6 +288,8 @@ API Changes consistency. * Pattern item PORT was renamed PHY_PORT to avoid confusion with DPDK port IDs. + * An action counterpart to the PHY_PORT pattern item was added in order to + redirect matching traffic to a specific physical port.
