Field Documentation

uint32_t key_size

Key size (number of bytes)

Examples:

ip_pipeline/pipeline/pipeline_flow_classification_be.c.

Definition at line 111 of file rte_table_hash.h.

uint32_t n_keys

Maximum number of keys

Definition at line 114 of file rte_table_hash.h.

uint32_t n_buckets

Number of hash table buckets. Each bucket stores up to 4 keys.

Definition at line 117 of file rte_table_hash.h.

uint32_t n_buckets_ext

Number of hash table bucket extensions. Each bucket extension has space for 4 keys and each bucket can have 0, 1 or more extensions.

Definition at line 121 of file rte_table_hash.h.

rte_table_hash_op_hash f_hash

Hash function

Definition at line 124 of file rte_table_hash.h.

uint64_t seed

Seed value for the hash function

Examples:

ip_pipeline/pipeline/pipeline_flow_classification_be.c.

Definition at line 127 of file rte_table_hash.h.

uint32_t signature_offset

Byte offset within packet meta-data where the 4-byte key signature is located. Valid for pre-computed key signature tables, ignored for do-sig tables.

Examples:

ip_pipeline/pipeline/pipeline_flow_classification_be.c.

Definition at line 132 of file rte_table_hash.h.

uint32_t key_offset

Byte offset within packet meta-data where the key is located

Definition at line 135 of file rte_table_hash.h.
