always used 8 bytes even if unneeded\n - this field is in the first half (cacheline) of mbuf\n\nAfter this series the dynamic field timestamp is used for both Rx and Tx\nwith separate dynamic flags to distinguish when the value is meaningful\nwithout resetting the field during forwarding.\n\nAs a consequence, 8 bytes can be re-allocated to dynamic fields,\nand bonus...\nthe mempool pointer can be promoted to the first half of mbuf!\n\nThis mbuf layout change is important to allow adding more features\n(consuming more dynamic fields) during the next year\nand can bring some performance improvement.\n\n\nThomas Monjalon (15):\n eventdev: remove software Rx timestamp\n mbuf: add Rx timestamp dynamic flag\n ethdev: register mbuf field and flags for timestamp\n latency: switch timestamp to dynamic mbuf field\n net/ark: switch timestamp to dynamic mbuf field\n net/dpaa2: switch timestamp to dynamic mbuf field\n net/mlx5: fix dynamic mbuf offset lookup check\n net/mlx5: switch

app/testpmd: switch timestamp to dynamic mbuf field\n examples/rxtx_callbacks: switch timestamp to dynamic field\n mbuf: remove deprecated timestamp field\n mbuf: move pool pointer in hotter first half\n\n app/test-pmd/config.c | 38 ----------\n app/test-pmd/util.c | 39 ++++++++++-\n app/test/test_mbuf.c | 1 -\n doc/guides/nics/mlx5.rst | 5 +-\n .../prog_guide/event_ethernet_rx_adapter.rst | 6
