This patchset add the IP reassembly RX offload. Currently, the offload is tested along with inline IPsec processing. It can also be updated as a standalone offload without IPsec, if there are some hardware available to test it. The patchset is tested on cnxk platform. The driver implementation and a test app are added as separate patchsets.[2][3] [1]: http://patches.dpdk.org/project/dpdk/patch/20210823100259.1619886-1-gakhil@marvell.com/ [2]: APP: http://patches.dpdk.org/project/dpdk/list/?series=21284 [3]: PMD: http://patches.dpdk.org/project/dpdk/list/?series=21285 Newer versions of app and PMD will be sent once library changes are acked. Changes in v6: - fix warnings. Changes in v5: - updated Doxygen comments.(Ferruh) - Added release notes. - updated libabigail suppress rules.(David) Changes in v4: - removed rte_eth_dev_info update for capability (Ferruh) - removed Rx offload flag (Ferruh) - added capability_get() (Ferruh) - moved dynfield and dynflag namedefines in rte_mbuf_dyn.h (Ferruh) changes in v3: - incorporated comments from Andrew and Stephen Hemminger changes in v2: - added abi ignore exceptions for modifications in reserved fields. Added a crude way to subside the rte_security and rte_ipsec ABI issue. Please suggest a better way. - incorporated Konstantin's comment for extra checks in new API introduced. - converted static mbuf ol_flag to mbuf dynflag (Konstantin) - added a get API for reassembly configuration (Konstantin) - Fixed checkpatch issues. - Dynfield is NOT split into 2 parts as it would cause an extra fetch in case of IP reassembly failure. - Application patches are split into a separate series.
