When\nRx queue is configured with header split feature with testpmd,\npackets received will be directly splited into two different\nmempools.\n\nXuan Ding (2):\n app/testpmd: add header split configuration\n net/ice: support header split in Rx data path\n\n app/test-pmd/cmdline.c | 85 +++++++++++\n app/test-pmd/testpmd.c | 6 +-\n app/test-pmd/testpmd.h | 2 +\n drivers/net/ice/ice_ethdev.c | 5 +-\n drivers/net/ice/ice_rxtx.c | 211 ++++++++++++++++++++++----\n drivers/net/ice/ice_rxtx.h | 15 ++\n drivers/net/ice/ice_rxtx_vec_common.h | 3 +\n 7 files changed, 295 insertions(+), 32 deletions(-)" }
