The generic rte_mbuf, containing a packet mbuf.
| 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 data_len |
Amount of data in segment buffer.
| struct { ... } fdir |
Filter identifier if FDIR enabled
| union { ... } hash |
hash information
| uint32_t hi |
First 4 flexible bytes or FD ID, dependent on PKT_RX_FDIR_* flag in ol_flags.
| uint64_t l2_len |
L2 (MAC) Header Length.
| uint64_t l3_len |
L3 (IP) Header Length.
| uint64_t l4_len |
L4 (TCP/UDP) Header Length.
| uint32_t lo |
Second 4 flexible bytes
| uint8_t nb_segs |
Number of segments.
| struct rte_mbuf* next |
Next segment of scattered packet.
| uint64_t ol_flags |
Offload features.
| uint64_t outer_l2_len |
Outer L2 (MAC) Hdr Length.
| uint64_t outer_l3_len |
Outer L3 (IP) Hdr Length.
| uint16_t packet_type |
The packet type, which is used to indicate ordinary packet and also tunneled packet format, i.e. each number is represented a type of packet.
| uint32_t pkt_len |
Total pkt len: sum of all segments.
| struct rte_mempool* pool |
Pool from which mbuf was allocated.
| uint8_t port |
Input port.
| uint16_t refcnt |
Non-atomically accessed refcnt
| rte_atomic16_t refcnt_atomic |
Atomically accessed refcnt
| uint32_t rss |
RSS hash result if RSS enabled
| uint32_t sched |
Hierarchical scheduler
| uint32_t seqn |
Sequence number. See also rte_reorder_insert()
| uint64_t tso_segsz |
TCP TSO segment size
| uint64_t tx_offload |
combined for easy fetch
| uint64_t udata64 |
Allow 8-byte userdata on 32-bit
| void* userdata |
Can be used for external metadata
| uint32_t usr |
User defined tags. See rte_distributor_process()
| uint16_t vlan_tci |
VLAN Tag Control Identifier (CPU order)
