The patchset introduced the cpfl (Control Plane Function Library) PMD for Intel® IPU E2100’s Configure Physical Function (Device ID: 0x1453) The cpfl PMD inherits all the features from idpf PMD which will follow an ongoing standard data plan function spec https://www.oasis-open.org/committees/tc_home.php?wg_abbrev=idpf Besides, it will also support more device specific hardware offloading features from DPDK’s control path (e.g.: hairpin, rte_flow …). which is different from idpf PMD, and that's why we need a new cpfl PMD. This patchset mainly focuses on idpf PMD’s equivalent features. To avoid duplicated code, the patchset depends on below patchsets which move the common part from net/idpf into common/idpf as a shared library. v2 changes: - rebase to the new baseline. - Fix rss lut config issue. v3 changes: - rebase to the new baseline. v4 changes: - Resend v3. No code changed. v5 changes: - rebase to the new baseline. - optimize some code - give "not supported" tips when user want to config rss hash type - if stats reset fails at initialization time, don't rollback, just print ERROR info v6 changes: - for small fixed size structure, change rte_memcpy to memcpy() - fix compilation for AVX512DQ - update cpfl maintainers v7 changes: - add dependency in cover-letter This patchset is based on the idpf PMD code: http://patches.dpdk.org/project/dpdk/cover/20230206054618.40975-1-beilei.xing@intel.com/ http://patches.dpdk.org/project/dpdk/cover/20230106090501.9106-1-beilei.xing@intel.com/ http://patches.dpdk.org/project/dpdk/cover/20230207084549.2225214-1-wenjun1.wu@intel.com/ http://patches.dpdk.org/project/dpdk/cover/20230208073401.2468579-1-mingxia.liu@intel.com/ Mingxia Liu (21): net/cpfl: support device initialization net/cpfl: add Tx queue setup net/cpfl: add Rx queue setup net/cpfl: support device start and stop net/cpfl: support queue start net/cpfl: support queue stop net/cpfl: support queue release net/cpfl: support MTU configuration net/cpfl: support basic Rx data path net/cpfl: support basic Tx data path net/cpfl: support write back based on ITR expire net/cpfl: support RSS net/cpfl: support Rx offloading net/cpfl: support Tx offloading net/cpfl: add AVX512 data path for single queue model net/cpfl: support timestamp offload net/cpfl: add AVX512 data path for split queue model net/cpfl: add HW statistics net/cpfl: add RSS set/get ops net/cpfl: support scalar scatter Rx datapath for single queue model net/cpfl: add xstats ops MAINTAINERS | 8 + doc/guides/nics/cpfl.rst | 88 ++ doc/guides/nics/features/cpfl.ini | 17 + doc/guides/rel_notes/release_23_03.rst | 6 + drivers/net/cpfl/cpfl_ethdev.c | 1453 +++++++++++++++++++++++ drivers/net/cpfl/cpfl_ethdev.h | 95 ++ drivers/net/cpfl/cpfl_logs.h | 32 + drivers/net/cpfl/cpfl_rxtx.c | 952 +++++++++++++++ drivers/net/cpfl/cpfl_rxtx.h | 44 + drivers/net/cpfl/cpfl_rxtx_vec_common.h | 116 ++ drivers/net/cpfl/meson.build | 40 + drivers/net/meson.build | 1 + 12 files changed, 2852 insertions(+) create mode 100644 doc/guides/nics/cpfl.rst create mode 100644 doc/guides/nics/features/cpfl.ini create mode 100644 drivers/net/cpfl/cpfl_ethdev.c create mode 100644 drivers/net/cpfl/cpfl_ethdev.h create mode 100644 drivers/net/cpfl/cpfl_logs.h create mode 100644 drivers/net/cpfl/cpfl_rxtx.c create mode 100644 drivers/net/cpfl/cpfl_rxtx.h create mode 100644 drivers/net/cpfl/cpfl_rxtx_vec_common.h create mode 100644 drivers/net/cpfl/meson.build

Currently, there is no related effort for standard idpf, but the vendors can enable their own hardware offloading feature based on idpf spec, (like cpfl), and the common/idpf can be leveraged.
