Add initial ntnic ethdev skeleton and register PCI probe functions Update documentation: Device description and feature list
Signed-off-by: Serhii Iliushyk <sil-...@napatech.com> --- v6 * Remove unused includes * Remove EOF markers * Remove unnecesarry commpiller flags * Update documentation INI and RST files * Remove uncovered features * Add features according to DPDK reqirements * Add link on NT200A02 description * Rename res(short for result) to ret(short for return) * Fix unnecessary set of the driver name * The driver name is set by macro RTE_PMD_REGISTER_PCI * Set sentinel value for PCI id_table * NULL value can lead to the crush on function rte_pci_match * Remove unnecessary comments v7 * Move features list to the dedicated patches * Update release note file --- .mailmap | 1 + MAINTAINERS | 7 ++++ doc/guides/nics/features/ntnic.ini | 8 +++++ doc/guides/nics/index.rst | 1 + doc/guides/nics/ntnic.rst | 39 ++++++++++++++++++++ doc/guides/rel_notes/release_24_07.rst | 10 ++++++ drivers/net/meson.build | 1 + drivers/net/ntnic/meson.build | 18 ++++++++++ drivers/net/ntnic/ntnic_ethdev.c | 49 ++++++++++++++++++++++++++ 9 files changed, 134 insertions(+) create mode 100644 doc/guides/nics/features/ntnic.ini create mode 100644 doc/guides/nics/ntnic.rst create mode 100644 drivers/net/ntnic/meson.build create mode 100644 drivers/net/ntnic/ntnic_ethdev.c diff --git a/.mailmap b/.mailmap index 552d79eaa6..aad8c552f6 100644 --- a/.mailmap +++ b/.mailmap @@ -1307,6 +1307,7 @@ Sergey Madaminov <sergey.madami...@gmail.com> Sergey Mironov <grr...@gmail.com> Sergey Temerkhanov <sergey.temerkha...@intel.com> Sergio Gonzalez Monroy <sergio.gonzalez.mon...@intel.com> +Serhii Iliushyk <sil-...@napatech.com> Seth Arnold <seth.arn...@canonical.com> Seth Howell <seth.how...@intel.com> Shachar Beiser <shacha...@mellanox.com> diff --git a/MAINTAINERS b/MAINTAINERS index 533f707d5f..0359368981 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -855,6 +855,13 @@ F: drivers/net/octeon_ep/ F: doc/guides/nics/features/octeon_ep.ini F: doc/guides/nics/octeon_ep.rst +Napatech ntnic +M: Christian Koue Muf <c...@napatech.com> +M: Serhii Iliushyk <sil-...@napatech.com> +F: drivers/net/ntnic/ +F: doc/guides/nics/ntnic.rst +F: doc/guides/nics/features/ntnic.ini + NVIDIA mlx4 M: Matan Azrad <ma...@nvidia.com> M: Viacheslav Ovsiienko <viachesl...@nvidia.com> diff --git a/doc/guides/nics/features/ntnic.ini b/doc/guides/nics/features/ntnic.ini new file mode 100644 index 0000000000..9ceb75a03b --- /dev/null +++ b/doc/guides/nics/features/ntnic.ini @@ -0,0 +1,8 @@ +; +; Supported features of the 'ntnic' network poll mode driver. +; +; Refer to default.ini for the full list of available PMD features. +; +[Features] +Linux = Y +x86-64 = Y diff --git a/doc/guides/nics/index.rst b/doc/guides/nics/index.rst index 7bfcac880f..c14bc7988a 100644 --- a/doc/guides/nics/index.rst +++ b/doc/guides/nics/index.rst @@ -53,6 +53,7 @@ Network Interface Controller Drivers nfb nfp ngbe + ntnic null octeon_ep octeontx diff --git a/doc/guides/nics/ntnic.rst b/doc/guides/nics/ntnic.rst new file mode 100644 index 0000000000..249d83d511 --- /dev/null +++ b/doc/guides/nics/ntnic.rst @@ -0,0 +1,39 @@ +..
