There are a number of HW tables of various\ntypes that could be used in MAE.\n\nIn some types of table the entry may also be associated with an\nN-bit \"mask\", allowing some bits of the request to be treated as\ndon't-care, and an integer \"priority\" to determine which entry is\nused if more than one matches.\n\nBCAM tables don't support \"mask\" and \"priority\", so the\ncorresponding fields must be zeroed.\n\nSigned-off-by: Denis Pryazhennikov <denis.pryazhennikov@arknetworks.am>\nReviewed-by: Ivan Malov <ivan.malov@arknetworks.am>\nReviewed-by: Andy Moreton <amoreton@xilinx.com>\n---\n drivers/net/sfc/sfc_tbls.h | 69 ++++++++++++++++++++++++++++++++++++++\n 1 file changed, 69 insertions(+)\n create mode 100644 drivers/net/sfc/sfc_tbls.h", "diff": "diff --git a/drivers/net/sfc/sfc_tbls.h b/drivers/net/sfc/sfc_tbls.h\nnew file mode 100644\nindex 0000000000..302f67224c\n--- /dev/null\n+++ b/drivers/net/sfc/sfc_tbls.h\n@@ -0,0 +1,69 @@\n+/* SPDX-License-Identifier: BSD-3-Clause\n+ *\n+ * Copyright (c) 2023 Advanced Micro Devices, Inc.\n+ */\n+\n+#ifndef _SFC_TBLS_H\n+#define _SFC_TBLS_H\n+\n+#include \"efx.h\"\n+\n+#ifdef __cplusplus\n+extern \"C\" {\n+#endif\n+\n+/*\n+ * Table types:\n+ * CAM - Content addressable memory\n+ * BCAM - Binary CAM\n+ * TCAM - Ternary CAM\n+ * STCAM - Semi-ternary CAM\n+ *\n+ * Short description:\n+ * TCAM: Each entry has a key, mask, response and priority.
