The timestamp is related to the global system timer Generally the first module (SW, TCL or TQM). that sees this frame and this timestamp field is not valid, shall fill in this field. Timestamp in units of 1024 us buffer_timestamp_valid When set, the Buffer_timestamp field contains valid info. reserved_4a hlos_tid_overwrite When set, TCL shall ignore the IP DSCP and VLAN PCP fields and use HLOS_TID as the final TID. Otherwise TCL shall consider the DSCP and PCP fields as well as HLOS_TID and choose a final TID based on the configured priority hlos_tid HLOS MSDU priority Field is used when HLOS_TID_overwrite is set. Field is also used when HLOS_TID_overwrite is not set and DSCP/PCP is not available in the packet lmac_id TCL uses this LMAC_ID in address search, i.e, while finding matching entry for the packet in AST corresponding to given LMAC_ID If LMAC ID is all 1s (=> value 3), it indicates wildcard match for any MAC reserved_4b dscp_tid_table_num DSCP to TID mapping table number that need to be used for the MSDU, should be specified using this field search_index The index that will be used for index based address or flow search. The field is valid when 'search_type' is 1 or 2. cache_set_num Cache set number that should be used to cache the index based search results, for address and flow search. This value should be equal to LSB four bits of the hash value of match data, in case of search index points to an entry which may be used in content based search also. The value can be anything when the entry pointed by search index will not be used for content based search. mesh_enable If set to a non-zero value: * For raw WiFi frames, this indicates transmission to a mesh STA, enabling the interpretation of the 'Mesh Control Present' bit (bit 8) of QoS Control (otherwise this bit is ignored). The interpretation of the A-MSDU 'Length' field is decided by the e-numerations below. * For native WiFi frames, this indicates that a 'Mesh Control' field is present between the header and the LLC. The three non-zero values are interchangeable. A-MSDU 'Length' is big endian and includes the length of Mesh Control. A-MSDU 'Length' is big endian and excludes the length of Mesh Control. A-MSDU 'Length' is little endian and excludes the length of Mesh Control. This is 802.11s-compliant. reserved_6a ring_id The buffer pointer ring ID. 0 refers to the IDLE ring 1 - N refers to other rings Helps with debugging when dumping ring contents. looping_count A count value that indicates the number of times the producer of entries into the Ring has looped around the ring. At initialization time, this value is set to 0. On the first loop, this value is set to 1. After the max value is reached allowed by the number of bits for this field, the count value continues with 0 again. In case SW is the consumer of the ring entries, it can use this field to figure out up to where the producer of entries has created new entries. This eliminates the need to check where the head pointer' of the ring is located once the SW starts processing an interrupt indicating that new entries have been put into this ring... Also note that SW if it wants only needs to look at the LSB bit of this count value. */ /* EXTERNAL REFERENCE : struct buffer_addr_info buf_addr_info */ /* Description TCL_DATA_CMD_0_BUF_ADDR_INFO_BUFFER_ADDR_31_0 Address (lower 32 bits) of the MSDU buffer OR MSDU_EXTENSION descriptor OR Link Descriptor In case of 'NULL' pointer, this field is set to 0 */ #define TCL_DATA_CMD_0_BUF_ADDR_INFO_BUFFER_ADDR_31_0_OFFSET 0x00000000 #define TCL_DATA_CMD_0_BUF_ADDR_INFO_BUFFER_ADDR_31_0_LSB 0 #define TCL_DATA_CMD_0_BUF_ADDR_INFO_BUFFER_ADDR_31_0_MASK 0xffffffff /* Description TCL_DATA_CMD_1_BUF_ADDR_INFO_BUFFER_ADDR_39_32 Address (upper 8 bits) of the MSDU buffer OR MSDU_EXTENSION descriptor OR Link Descriptor In case of 'NULL' pointer, this field is set to 0 */ #define TCL_DATA_CMD_1_BUF_ADDR_INFO_BUFFER_ADDR_39_32_OFFSET 0x00000004 #define TCL_DATA_CMD_1_BUF_ADDR_INFO_BUFFER_ADDR_39_32_LSB 0 #define TCL_DATA_CMD_1_BUF_ADDR_INFO_BUFFER_ADDR_39_32_MASK 0x000000ff /* Description TCL_DATA_CMD_1_BUF_ADDR_INFO_RETURN_BUFFER_MANAGER Consumer: WBM Producer: SW/FW In case of 'NULL' pointer, this field is set to 0 Indicates to which buffer manager the buffer OR MSDU_EXTENSION descriptor OR link descriptor that is being pointed to shall be returned after the frame has been processed.

The three non-zero values are interchangeable. A-MSDU 'Length' is big endian and includes the length of Mesh Control. A-MSDU 'Length' is big endian and excludes the length of Mesh Control. A-MSDU 'Length' is little endian and excludes the length of Mesh Control. This is 802.11s-compliant. */ #define TCL_DATA_CMD_5_MESH_ENABLE_OFFSET 0x00000014 #define TCL_DATA_CMD_5_MESH_ENABLE_LSB 30 #define TCL_DATA_CMD_5_MESH_ENABLE_MASK 0xc0000000 /* Description TCL_DATA_CMD_6_RESERVED_6A */ #define TCL_DATA_CMD_6_RESERVED_6A_OFFSET 0x00000018 #define TCL_DATA_CMD_6_RESERVED_6A_LSB 0 #define TCL_DATA_CMD_6_RESERVED_6A_MASK 0x000fffff /* Description TCL_DATA_CMD_6_RING_ID The buffer pointer ring ID. 0 refers to the IDLE ring 1 - N refers to other rings Helps with debugging when dumping ring contents. */ #define TCL_DATA_CMD_6_RING_ID_OFFSET 0x00000018 #define TCL_DATA_CMD_6_RING_ID_LSB 20 #define TCL_DATA_CMD_6_RING_ID_MASK 0x0ff00000 /* Description TCL_DATA_CMD_6_LOOPING_COUNT A count value that indicates the number of times the producer of entries into the Ring has looped around the ring. At initialization time, this value is set to 0. On the first loop, this value is set to 1. After the max value is reached allowed by the number of bits for this field, the count value continues with 0 again. In case SW is the consumer of the ring entries, it can use this field to figure out up to where the producer of entries has created new entries. This eliminates the need to check where the head pointer' of the ring is located once the SW starts processing an interrupt indicating that new entries have been put into this ring... Also note that SW if it wants only needs to look at the LSB bit of this count value. */ #define TCL_DATA_CMD_6_LOOPING_COUNT_OFFSET 0x00000018 #define TCL_DATA_CMD_6_LOOPING_COUNT_LSB 28 #define TCL_DATA_CMD_6_LOOPING_COUNT_MASK 0xf0000000 #endif // _TCL_DATA_CMD_H_
