Introducing port representor support to CNXK drivers by adding virtual ethernet ports providing a logical representation in DPDK for physical function(PF) or SR-IOV virtual function (VF) devices for control and monitoring.
These port representor ethdev instances can be spawned on an as needed basis through configuration parameters passed to the driver of the underlying base device using devargs ``-a <base PCI BDF>,representor=pf*vf*`` In case of exception path (i.e. until the flow definition is offloaded to the hardware), packets transmitted by the VFs shall be received by these representor port, while packets transmitted by representor ports shall be received by respective VFs. On receiving the VF traffic via these representor ports, applications holding these representor ports can decide to offload the traffic flow into the HW. Henceforth the matching traffic shall be directly steered to the respective VFs without being received by the application. Current virtual representor port PMD supports following operations: - Get represented port statistics - Flow operations - create, validate, destroy, query, flush, dump Changes since V2: * Moved devargs parsing logic to common code and sent as separate series * Documentation updated * Addressed comments from V2 Changes since V1: * Updated communication layer between representor and represented port. * Added support for native represented ports * Port representor and represented port item and action support * Build failure fixes Harman Kalra (21): common/cnxk: add support for representors net/cnxk: implementing eswitch device net/cnxk: eswitch HW resource configuration net/cnxk: eswitch devargs parsing net/cnxk: probing representor ports common/cnxk: common NPC changes for eswitch common/cnxk: interface to update VLAN TPID net/cnxk: eswitch flow configurations net/cnxk: eswitch fastpath routines net/cnxk: add representor control plane common/cnxk: representee notification callback net/cnxk: handling representee notification net/cnxk: representor ethdev ops common/cnxk: get representees ethernet stats net/cnxk: ethernet statistic for representor common/cnxk: base support for eswitch VF net/cnxk: eswitch VF as ethernet device net/cnxk: add representor port pattern and action net/cnxk: generalise flow operation APIs net/cnxk: flow create on representor ports net/cnxk: other flow operations Kiran Kumar K (2): common/cnxk: support port representor and represented port net/cnxk: add represented port pattern and action MAINTAINERS | 1 + doc/guides/nics/cnxk.rst | 41 ++ doc/guides/nics/features/cnxk.ini | 5 + doc/guides/nics/features/cnxk_vec.ini | 6 + doc/guides/nics/features/cnxk_vf.ini | 6 + drivers/common/cnxk/meson.build | 1 + drivers/common/cnxk/roc_api.h | 3 + drivers/common/cnxk/roc_constants.h | 2 + drivers/common/cnxk/roc_dev.c | 25 + drivers/common/cnxk/roc_dev_priv.h | 3 + drivers/common/cnxk/roc_eswitch.c | 389 +++++++++++ drivers/common/cnxk/roc_eswitch.h | 34 + drivers/common/cnxk/roc_mbox.c | 2 + drivers/common/cnxk/roc_mbox.h | 82 ++- drivers/common/cnxk/roc_nix.c | 46 +- drivers/common/cnxk/roc_nix.h | 4 + drivers/common/cnxk/roc_nix_priv.h | 12 +- drivers/common/cnxk/roc_nix_vlan.c | 23 +- drivers/common/cnxk/roc_npc.c | 89 ++- drivers/common/cnxk/roc_npc.h | 18 +- drivers/common/cnxk/roc_npc_mcam.c | 64 +- drivers/common/cnxk/roc_npc_parse.c | 28 +- drivers/common/cnxk/roc_npc_priv.h | 5 +- drivers/common/cnxk/roc_platform.c | 2 + drivers/common/cnxk/roc_platform.h | 4 + drivers/common/cnxk/version.map | 14 + drivers/net/cnxk/cn10k_ethdev.c | 1 + drivers/net/cnxk/cnxk_eswitch.c | 807 +++++++++++++++++++++++ drivers/net/cnxk/cnxk_eswitch.h | 213 ++++++ drivers/net/cnxk/cnxk_eswitch_devargs.c | 125 ++++ drivers/net/cnxk/cnxk_eswitch_flow.c | 454 +++++++++++++ drivers/net/cnxk/cnxk_eswitch_rxtx.c | 211 ++++++ drivers/net/cnxk/cnxk_ethdev.c | 41 +- drivers/net/cnxk/cnxk_ethdev.h | 3 + drivers/net/cnxk/cnxk_ethdev_ops.c | 4 + drivers/net/cnxk/cnxk_flow.c | 546 ++++++++++++---- drivers/net/cnxk/cnxk_flow.h | 27 +- drivers/net/cnxk/cnxk_link.c | 3 +- drivers/net/cnxk/cnxk_rep.c | 555 ++++++++++++++++ drivers/net/cnxk/cnxk_rep.h | 141 ++++ drivers/net/cnxk/cnxk_rep_flow.c | 815 +++++++++++++++++++++++ drivers/net/cnxk/cnxk_rep_msg.c | 827 ++++++++++++++++++++++++ drivers/net/cnxk/cnxk_rep_msg.h | 169 +++++ drivers/net/cnxk/cnxk_rep_ops.c | 715 ++++++++++++++++++++ drivers/net/cnxk/meson.build | 8 + 45 files changed, 6371 insertions(+), 203 deletions(-) create mode 100644 drivers/common/cnxk/roc_eswitch.c create mode 100644 drivers/common/cnxk/roc_eswitch.h create mode 100644 drivers/net/cnxk/cnxk_eswitch.c create mode 100644 drivers/net/cnxk/cnxk_eswitch.h create mode 100644 drivers/net/cnxk/cnxk_eswitch_devargs.c create mode 100644 drivers/net/cnxk/cnxk_eswitch_flow.c create mode 100644 drivers/net/cnxk/cnxk_eswitch_rxtx.c create mode 100644 drivers/net/cnxk/cnxk_rep.c create mode 100644 drivers/net/cnxk/cnxk_rep.h create mode 100644 drivers/net/cnxk/cnxk_rep_flow.c create mode 100644 drivers/net/cnxk/cnxk_rep_msg.c create mode 100644 drivers/net/cnxk/cnxk_rep_msg.h create mode 100644 drivers/net/cnxk/cnxk_rep_ops.c -- 2.18.0
