34 #define __CVMX_PACKET_H__
37 * This structure defines a buffer pointer on Octeon
44 * if set, invert the "free" pick of the overall
45 * packet. HW always sets this bit to 0 on inbound
50 * Indicates the amount to back up to get to the
51 * buffer start in cache lines. In most cases this is
52 * less than one complete cache line, so the value is
56 /* The pool that the buffer came from / goes to */
58 /* The size of the segment pointed to by addr (in bytes) */
60 /* Pointer to the first byte of the data, NOT buffer */
