NAME

rte_acl_field_def

SYNOPSIS

#include <rte_acl.h>

Data Fields


uint8_t type
uint8_t size
uint8_t field_index
uint8_t input_index
uint32_t offset

Detailed Description

ACL Field definition. Each field in the ACL rule has an associate definition. It defines the type of field, its size, its offset in the input buffer, the field index, and the input index. For performance reasons, the inner loop of the search function is unrolled to process four input bytes at a time. This requires the input to be grouped into sets of 4 consecutive bytes. The loop processes the first input byte as part of the setup and then subsequent bytes must be in groups of 4 consecutive bytes.
