It help to identify the ring that is being looked looping_count Consumer: WBM/SW/FW Producer: SW/TQM/RXDMA/REO/SWITCH A count value that indicates the number of times the producer of entries into the Buffer Manager 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 WBM_RELEASE_RING_0_BUFFER_ADDR_INFO_RELEASED_BUFF_OR_DESC_ADDR_INFO_OFFSET 0x00000000 #define WBM_RELEASE_RING_0_BUFFER_ADDR_INFO_RELEASED_BUFF_OR_DESC_ADDR_INFO_LSB 28 #define WBM_RELEASE_RING_0_BUFFER_ADDR_INFO_RELEASED_BUFF_OR_DESC_ADDR_INFO_MASK 0xffffffff #define WBM_RELEASE_RING_1_BUFFER_ADDR_INFO_RELEASED_BUFF_OR_DESC_ADDR_INFO_OFFSET 0x00000004 #define WBM_RELEASE_RING_1_BUFFER_ADDR_INFO_RELEASED_BUFF_OR_DESC_ADDR_INFO_LSB 28 #define WBM_RELEASE_RING_1_BUFFER_ADDR_INFO_RELEASED_BUFF_OR_DESC_ADDR_INFO_MASK 0xffffffff /* Description WBM_RELEASE_RING_2_RELEASE_SOURCE_MODULE Indicates which module initiated the release of this buffer or descriptor TQM released this buffer or descriptor RXDMA released this buffer or descriptor REO released this buffer or descriptor FW released this buffer or descriptor SW released this buffer or descriptor */ #define WBM_RELEASE_RING_2_RELEASE_SOURCE_MODULE_OFFSET 0x00000008 #define WBM_RELEASE_RING_2_RELEASE_SOURCE_MODULE_LSB 0 #define WBM_RELEASE_RING_2_RELEASE_SOURCE_MODULE_MASK 0x00000007 /* Description WBM_RELEASE_RING_2_BM_ACTION Consumer: WBM/SW/FW Producer: SW/TQM/RXDMA/REO/SWITCH Field only valid when the field return_buffer_manager in the Released_buff_or_desc_addr_info indicates: WBM_IDLE_BUF_LIST or WBM_IDLE_DESC_LIST An MSDU extension descriptor shall never be marked as Put the buffer or descriptor back in the idle list.
