Lines Matching full:circular

880  * up to 7 DMA channels (FIFOs).  Each Tx queue is supported by a circular array
966  * TFD Circular Buffers Base (CBBC) addresses
969  * circular buffers (CBs/queues) containing Transmit Frame Descriptors (TFDs)
971  * bytes from one another.  Each TFD circular buffer in DRAM must be 256-byte
997  * 1)  Receive Buffer Descriptor (RBD) circular buffer (CB), typically with 256
1007  *     Driver sets physical address [35:8] of base of RBD circular buffer
1012  *     the RB's corresponding RBD within the circular buffer.  Driver sets
1022  * enter pointers to these RBs into contiguous RBD circular buffer entries,
1028  * the circular buffer.  This value should initially be 0 (before preparing any
1030  * wrap back to 0 at the end of the circular buffer (but don't wrap before
1034  * As the 4965 fills RBs (referenced from contiguous RBDs within the circular
1064  * Physical base address of Rx Buffer Descriptor Circular Buffer.
1074  *         NOTE:  For 256-entry circular buffer, use only bits [7:0].
1094  * 23-20: # RBDs in circular buffer = 2^value; use "8" for 256 RBDs (normal),
