Field Documentation

void* buf_addr

Virtual address of segment buffer.

Definition at line 393 of file rte_mbuf.h.

phys_addr_t buf_physaddr

Physical address of segment buffer.

Definition at line 394 of file rte_mbuf.h.

uint16_t buf_len

Length of segment buffer.

Definition at line 396 of file rte_mbuf.h.

rte_atomic16_t refcnt_atomic

Atomically accessed refcnt

Definition at line 412 of file rte_mbuf.h.

uint16_t refcnt

Non-atomically accessed refcnt

Definition at line 413 of file rte_mbuf.h.

RTE_STD_C11 { ... }

16-bit Reference counter. 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 CONFIG_RTE_MBUF_REFCNT_ATOMIC config option.

uint8_t nb_segs

Number of segments.
