same field\n for different purposes, with a risk of usage conflict.\n - this field always used 8 bytes even if unneeded\n\nSome dynamic fields are created when needed to replace\nthe big static userdata field.\nAs a consequence, 8 bytes can be re-allocated to dynamic fields.\n\nThis mbuf layout change is important to allow adding more features\n(consuming more dynamic fields) during the next year.\n\n\nv4 (thanks Jerin, Nithin and Ed):\n- move rte_node dynfield offset to hotter context in cache\n- move test-eventdev dynfield offset to hotter context in cache\n- split ARK user data for Rx and Tx + more ARK fixes\n\nv3 (thanks Olivier):\n- use typedef for new field types\n- fix node field type\n- initialize offsets to -1\n- add more inline functions\n- inline rte_security_dynfield_is_registered\n- add PMD-specific userdata field for ARK\n\nv2 (thanks David & Andrew):\n- fix some indentations\n- return -rte_errno consistently\n- make some type casts more precise\n- define dynfield types in macros\n- hide field description in rte_security\n- do not lookup security dynfield in ipsec-secgw\n- do not use the existing timestamp field for other purpose\n\n\nEd Czeck (1):\n net/ark: switch user data to dynamic mbuf fields\n\nNithin Dabilpuram (1):\n node: switch IPv4 metadata to dynamic mbuf field\n\nThomas Monjalon (13):\n examples: enclose
