Detailed Description

The generic rte_mbuf, containing a packet mbuf or a control mbuf.

Field Documentation

union { ... }

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.

void* buf_addr

Virtual address of segment buffer.

uint16_t buf_len

Length of segment buffer.

phys_addr_t buf_physaddr

Physical address of segment buffer.

uint16_t ol_flags

Offload features.

struct rte_mempool* pool

Pool from which mbuf was allocated.

uint16_t refcnt

Non-atomically accessed refcnt

rte_atomic16_t refcnt_atomic

Atomically accessed refcnt

uint8_t reserved

Unused field. Required for padding.

uint8_t type

Type of mbuf.
