This patch set adds an IAVF testpmd command "set tx lldp on|off" which will register an mbuf dynfield IAVF_TX_LLDP_DYNFIELD, currently only supported turning on.
IAVF will fill the SWTCH_UPLINK bit in the Tx context descriptor based on the mbuf dynfield to send the LLDP packet. For avx512, need to close the Tx port first, then "set tx lldp on", and reopen the port to select correct Tx path. --- v4: fix compile error v3: non-lldp packet do not use the context descriptor v2: split into patch set, refine commit log Zhichao Zeng (3): net/iavf: support Tx LLDP on scalar net/iavf: support Tx LLDP on AVX512 net/iavf: add Tx LLDP command doc/guides/rel_notes/release_24_03.rst | 3 + drivers/net/iavf/iavf_ethdev.c | 1 + drivers/net/iavf/iavf_rxtx.c | 21 ++++++- drivers/net/iavf/iavf_rxtx.h | 6 ++ drivers/net/iavf/iavf_rxtx_vec_avx512.c | 19 ++++++ drivers/net/iavf/iavf_rxtx_vec_common.h | 5 ++ drivers/net/iavf/iavf_testpmd.c | 82 +++++++++++++++++++++++++ drivers/net/iavf/meson.build | 3 + 8 files changed, 138 insertions(+), 2 deletions(-) create mode 100644 drivers/net/iavf/iavf_testpmd.c -- 2.34.1
