This patchset aims to fix this limitation transparently to the end user. It will also enable compatibility with the latest AF_XDP Device Plugin. Signed-off-by: Maryam Tahhan --- v8: * Go back to using `use_cni` vdev argument * Introduce `use_map_pinning` vdev param. * Rename `uds_path` to `dp_path` so that it can be used with map pinning as well as `use_cni`. * Set `dp_path` internally in the AF_XDP PMD if it's not configured by the user. * Clean up the original `use_cni` documentation separately to coding changes. v7: * Give a more descriptive commit msg headline. * Fixup typos in documentation. v6: * Add link to PR 81 in commit message * Add release notes changes to this patchset v5: * Fix alignment for ETH_AF_XDP_USE_DP_UDS_PATH_ARG * Remove use_cni references in af_xdp.rst v4: * Rename af_xdp_cni.rst to af_xdp_dp.rst * Removed all incorrect references to CNI throughout af_xdp PMD file. * Fixed Typos in af_xdp_dp.rst v3: * Remove `use_cni` vdev argument as it's no longer needed. * Update incorrect CNI references for the AF_XDP DP in the documentation. * Update the documentation to run a simple example with the AF_XDP DP plugin in K8s. v2: * Rename sock_path to uds_path. * Update documentation to reflect when CAP_BPF is needed. * Fix testpmd arguments in the provided example for Pods. * Use AF_XDP API to update the xskmap entry. --- Maryam Tahhan (3): docs: AF_XDP Device Plugin net/af_xdp: fix multi interface support for K8s net/af_xdp: support AF_XDP DP pinned maps doc/guides/howto/af_xdp_cni.rst | 253 ------------------ doc/guides/howto/af_xdp_dp.rst | 349 +++++++++++++++++++++++++ doc/guides/howto/index.rst | 2 +- doc/guides/nics/af_xdp.rst | 44 +++- doc/guides/rel_notes/release_24_03.rst | 17 ++ drivers/net/af_xdp/rte_eth_af_xdp.c | 162 ++++++++---- 6 files changed, 527 insertions(+), 300 deletions(-) delete mode 100644 doc/guides/howto/af_xdp_cni.rst create mode 100644 doc/guides/howto/af_xdp_dp.rst
