Field Documentation

enum rte_eth_rx_mq_mode mq_mode

The multi-queue packet distribution mode to be used, e.g. RSS.

Definition at line 323 of file rte_ethdev.h.

uint32_t max_rx_pkt_len

Only used if jumbo_frame enabled.

Examples:

examples/flow_classify/flow_classify.c, examples/ip_fragmentation/main.c, examples/ip_reassembly/main.c, examples/ipsec-secgw/ipsec-secgw.c, examples/ipv4_multicast/main.c, examples/l2fwd-cat/l2fwd-cat.c, examples/l3fwd-acl/main.c, examples/l3fwd-power/main.c, examples/l3fwd/main.c, examples/performance-thread/l3fwd-thread/main.c, examples/ptpclient/ptpclient.c, examples/qos_sched/init.c, examples/rxtx_callbacks/main.c, examples/skeleton/basicfwd.c, examples/vhost/main.c, and examples/vm_power_manager/main.c.

Definition at line 324 of file rte_ethdev.h.

uint16_t split_hdr_size

hdr buf size (header_split enabled).

Examples:

examples/flow_filtering/main.c, examples/l2fwd-jobstats/main.c, examples/l2fwd-keepalive/main.c, examples/l2fwd/main.c, examples/link_status_interrupt/main.c, examples/multi_process/l2fwd_fork/main.c, examples/netmap_compat/bridge/bridge.c, examples/quota_watermark/qw/init.c, and examples/tep_termination/vxlan_setup.c.

Definition at line 325 of file rte_ethdev.h.

uint64_t offloads

Per-port Rx offloads to be set using DEV_RX_OFFLOAD_* flags. Only offloads set on rx_offload_capa field on rte_eth_dev_info structure are allowed to be set.

Examples:

examples/bond/main.c, examples/exception_path/main.c, examples/flow_filtering/main.c, examples/ip_fragmentation/main.c, examples/ip_reassembly/main.c, examples/ipsec-secgw/ipsec-secgw.c, examples/ipv4_multicast/main.c, examples/kni/main.c, examples/l2fwd-crypto/main.c, examples/l2fwd-jobstats/main.c, examples/l2fwd-keepalive/main.c, examples/l2fwd/main.c, examples/l3fwd-acl/main.c, examples/l3fwd-power/main.c, examples/l3fwd-vf/main.c, examples/l3fwd/main.c, examples/link_status_interrupt/main.c, examples/load_balancer/init.c, examples/multi_process/l2fwd_fork/main.c, examples/multi_process/symmetric_mp/main.c, examples/performance-thread/l3fwd-thread/main.c, examples/qos_meter/main.c, examples/qos_sched/init.c, examples/quota_watermark/qw/init.c, examples/tep_termination/vxlan_setup.c, and examples/vhost/main.c.

Definition at line 331 of file rte_ethdev.h.

__extension__ uint16_t header_split

Below bitfield API is obsolete. Application should enable per-port offloads using the offload field above.Header Split enable.

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t hw_ip_checksum

IP/UDP/TCP checksum offload enable.

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t hw_vlan_filter

VLAN filter enable.

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t hw_vlan_strip

VLAN strip enable.

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t hw_vlan_extend

Extended VLAN enable.

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t jumbo_frame

Jumbo Frame Receipt enable.

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t hw_strip_crc

Enable CRC stripping by hardware.

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t enable_scatter

Enable scatter packets rx handler

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t enable_lro

Enable LRO

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t hw_timestamp

Enable HW timestamp

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t security

Enable rte_security offloads

Definition at line 338 of file rte_ethdev.h.

__extension__ uint16_t ignore_offload_bitfield

When set the offload bitfield should be ignored. Instead per-port Rx offloads should be set on offloads field above. Per-queue offloads shuold be set on rte_eth_rxq_conf structure. This bit is temporary till rxmode bitfield offloads API will be deprecated.

Examples:

examples/exception_path/main.c, examples/kni/main.c, and examples/packet_ordering/main.c.
