The generic rte_mbuf, containing a packet mbuf.
Definition at line 473 of file rte_mbuf_core.h.
rte_iova_t buf_iova __rte_aligned | ( | sizeof(rte_iova_t) | ) |
Physical address of segment buffer. Force alignment to 8-bytes, so as to ensure we have the exact same mbuf cacheline0 layout for 32-bit and 64-bit. This makes working on vector drivers easier.
void* buf_addr |
Virtual address of segment buffer.
Definition at line 476 of file rte_mbuf_core.h.
uint16_t refcnt |
Reference counter. Its size should at least equal to the size of port field (16 bits), to support zero-copy broadcast. It should only be accessed using the following functions: rte_mbuf_refcnt_update(), rte_mbuf_refcnt_read(), and rte_mbuf_refcnt_set(). The functionality of these functions (atomic, or non-atomic) is controlled by the RTE_MBUF_REFCNT_ATOMIC flag.
