The primary reason was because there could not be more\nthan one HW profile with the same CDID, PTG, and VSIG. The Direction\nmetadata was not a parameter used to select HW profile IDs.\n\nThus, for ACL, the direction flag would need to be added to the extraction\nsequence. This information will be use later as one criteria for ACL\nscenario entry matching.\n\nSigned-off-by: Chinh T Cao <chinh.t.cao@intel.com>\nSigned-off-by: Paul M Stillwell Jr <paul.m.stillwell.jr@intel.com>\nSigned-off-by: Leyi Rong <leyi.rong@intel.com>\n---\n drivers/net/ice/base/ice_flow.c | 43 +++++++++++++++++++++++++++++++++\n 1 file changed, 43 insertions(+)", "diff": "diff --git a/drivers/net/ice/base/ice_flow.c b/drivers/net/ice/base/ice_flow.c\nindex be819e0e9..f1bf5b5e7 100644\n--- a/drivers/net/ice/base/ice_flow.c\n+++ b/drivers/net/ice/base/ice_flow.c\n@@ -495,6 +495,42 @@ ice_flow_proc_seg_hdrs(struct ice_flow_prof_params *params)\n \treturn ICE_SUCCESS;\n }\n \n+/**\n+ * ice_flow_xtract_pkt_flags - Create an extr sequence entry for packet flags\n+ * @hw: pointer to the HW struct\n+ * @params: information about the flow to be processed\n+ * @flags: The value of pkt_flags[x:x] in RX/TX MDID metadata.\n+ *\n+ * This function will allocate an extraction sequence entries for a DWORD size\n+ * chunk of the packet flags.\n+ */\n+static enum ice_status\n+ice_flow_xtract_pkt_flags(struct ice_hw *hw,\n+\t\t\t struct ice_flow_prof_params *params,\n+\t\t\t enum ice_flex_mdid_pkt_flags flags)\n+{\n+\tu8 fv_words = hw->blk[params->blk].es.fvw;\n+\tu8 idx;\n+\n+\t/* Make sure the number of extraction sequence entries required does not\n+\t * exceed the block's capacity.\n+\t */\n+\tif (params->es_cnt >= fv_words)\n+\t\treturn ICE_ERR_MAX_LIMIT;\n+\n+\t/* some blocks require a reversed field vector layout */\n+\tif (hw->blk[params->blk].es.reverse)\n+\t\tidx = fv_words - params->es_cnt - 1;\n+\telse\n+\t\tidx = params->es_cnt;\n+\n+\tparams->es[idx].prot_id = ICE_PROT_META_ID;\n+\tparams->es[idx].off = flags;\n+\tparams->es_cnt++;\n+\n+\treturn ICE_SUCCESS;\n+}\n+\n /**\n * ice_flow_xtract_fld - Create an extraction sequence entry for the given field\n * @hw: pointer to the HW struct\n@@ -744,6 +780,13 @@ ice_flow_create_xtrct_seq(struct ice_hw *hw,\n \tenum ice_status status = ICE_SUCCESS;\n \tu8 i;\n \n+\t/* For ACL, we also need to extract the direction bit (Rx,Tx) data from\n+\t * packet flags\n+\t */\n+\tif (params->blk == ICE_BLK_ACL)\n+\t\tice_flow_xtract_pkt_flags(hw, params,\n+\t\t\t\t\t ICE_RX_MDID_PKT_FLAGS_15_0);\n+\n \tfor (i = 0; i < params->prof->segs_cnt; i++) {\n \t\tu64 match = params->prof->segs[i].match;\n \t\tu16 j;\n", "prefixes": [ "02/49" ] }
