Currently, there is a\nscenario in which multiple TCAM blocks are cascaded. It means the\ntotal entries are 512. The default priority is NORMAL, so the max\nentry is 256, not 512. This patch changes the max entry number for\nNORMAL priority.\n\nFixes: 40d466fa9f76 (\"net/ice: support ACL filter in DCF\")\n\nSigned-off-by: Simei Su <simei.su@intel.com>\n---\n drivers/net/ice/ice_acl_filter.c | 4 ++--\n drivers/net/ice/ice_ethdev.h | 4 ++--\n 2 files changed, 4 insertions(+), 4 deletions(-)", "diff": "diff --git a/drivers/net/ice/ice_acl_filter.c b/drivers/net/ice/ice_acl_filter.c\nindex 3375609..0c15a70 100644\n--- a/drivers/net/ice/ice_acl_filter.c\n+++ b/drivers/net/ice/ice_acl_filter.c\n@@ -430,7 +430,7 @@ ice_acl_hw_set_conf(struct ice_pf *pf, struct ice_fdir_fltr *input,\n \t/* For IPV4_OTHER type, should add entry for all types.\n \t * For IPV4_UDP/TCP/SCTP type, only add entry for each.\n \t */\n-\tif (slot_id < MAX_ACL_ENTRIES) {\n+\tif (slot_id < MAX_ACL_NORMAL_ENTRIES) {\n \t\tentry_id = ((uint64_t)flow_type << 32) | slot_id;\n \t\tret = ice_flow_add_entry(hw, blk, flow_type,\n \t\t\t\t\t entry_id, pf->main_vsi->idx,\n@@ -444,7 +444,7 @@ ice_acl_hw_set_conf(struct ice_pf *pf, struct ice_fdir_fltr *input,\n \t\tpf->acl.hw_entry_id[slot_id] = hw_entry;\n \t} else {\n \t\tPMD_DRV_LOG(ERR, \"Exceed the maximum entry number(%d)\"\n-\t\t\t \" HW supported!\", MAX_ACL_ENTRIES);\n+\t\t\t \" HW supported!\", MAX_ACL_NORMAL_ENTRIES);\n \t\treturn -1;\n \t}\n \ndiff --git a/drivers/net/ice/ice_ethdev.h b/drivers/net/ice/ice_ethdev.h\nindex edafdf1..b4bf651 100644\n--- a/drivers/net/ice/ice_ethdev.h\n+++ b/drivers/net/ice/ice_ethdev.h\n@@ -50,7 +50,7 @@\n #define ICE_PKG_FILE_SEARCH_PATH_UPDATES \"/lib/firmware/updates/intel/ice/ddp/\"\n #define ICE_MAX_PKG_FILENAME_SIZE 256\n \n-#define MAX_ACL_ENTRIES 512\n+#define MAX_ACL_NORMAL_ENTRIES 256\n \n /**\n * vlan_id is a 12 bit number.\n@@ -408,7 +408,7 @@ struct ice_acl_conf {\n struct ice_acl_info {\n \tstruct ice_acl_conf conf;\n \tstruct rte_bitmap *slots;\n-\tuint64_t hw_entry_id[MAX_ACL_ENTRIES];\n+\tuint64_t hw_entry_id[MAX_ACL_NORMAL_ENTRIES];\n };\n \n struct ice_pf {\n", "prefixes": [] }
