Also, NEON vector path has been added to iavf_set_rx_function. Functional testing with testpmd (rxonly and mac forwarding) and l3fwd have been done on N1SDP platform. Performance testing will be done when Tx path is implemented. FDIR extraction will be added at a later point as well. Scatter and flex Rx paths will be deferred until a later release. --- v2: * Fixed compiler warning for PPC arch v3 * Updated commit message with testpmd rxonly mode test results Kathleen Capella (1): net/iavf: add vector PMD for Arm for basic Rx path drivers/net/iavf/iavf_rxtx.c | 18 +- drivers/net/iavf/iavf_rxtx_vec_neon.c | 415 ++++++++++++++++++++++++++ drivers/net/iavf/meson.build | 2 + 3 files changed, 434 insertions(+), 1 deletion(-) create mode 100644 drivers/net/iavf/iavf_rxtx_vec_neon.c
