Currently, key\nfield is supported with pattern gre_key item '.. / gre / gre_key value is\nxx / ..' with field gre_key in misc, but misc does not support matching of\nchecksum and sequence number of GRE.\nTo support matching of checksum and sequence number fields in GRE,\nrdma-core needs the capbility of misc5 and support tunnel_header 0-3. Since\ntunnel_header1 is used to match checksum, tunnel_header2 for key and\ntunnel_header3 for sequence by hardware. If checksum and sequence number\nnot present in the pattern, use misc as before for the matching.\nApplication can still use gre_key item 'gre_key value is xx' for key\nmatching, the effect is the same if use 'gre_option key is xx'.\nIf using gre_option item, the flags in gre item should be correspondingly\nset. For example, if using gre_option to match checksum, the c_bit should\nbe set '1' (.. / gre c_bit is 1 / gre_option checksum is xx / ..).\n\nSean Zhang (4):\n lib: add optional fields in GRE header\n ethdev: support GRE optional fields\n app/testpmd: add gre_option item command\n net/mlx5: support matching optional fields of GRE\n\n app/test-pmd/cmdline_flow.c | 59 +++++++++++\n doc/guides/prog_guide/rte_flow.rst | 17 ++++\n doc/guides/testpmd_app_ug/testpmd_funcs.rst | 6 ++\n drivers/common/mlx5/mlx5_devx_cmds.c | 3 +\n drivers/net/mlx5/linux/mlx5_os.c | 2 +\n drivers/net/mlx5/mlx5.h | 1 +\n drivers/net/mlx5/mlx5_flow.c | 106 ++++++++++++++++++++\n drivers/net/mlx5/mlx5_flow.h | 6 ++\n drivers/net/mlx5/mlx5_flow_dv.c | 146 ++++++++++++++++++++++++++++\n lib/ethdev/rte_flow.c | 1 +\n lib/ethdev/rte_flow.h | 19 ++++\n lib/net/rte_gre.h | 21 ++++\n 12 files changed, 387 insertions(+)" }
