SYNOPSIS

#include <rte_flow.h>

Data Fields


uint32_t relative:1
uint32_t search:1
uint32_t reserved:30
int32_t offset
uint16_t limit
uint16_t length
const uint8_t * pattern

Detailed Description

RTE_FLOW_ITEM_TYPE_RAW

Matches a byte string of a given length at a given offset.

Offset is either absolute (using the start of the packet) or relative to the end of the previous matched item in the stack, in which case negative values are allowed.

If search is enabled, offset is used as the starting point. The search area can be delimited by setting limit to a nonzero value, which is the maximum number of bytes after offset where the pattern may start.

Matching a zero-length pattern is allowed, doing so resets the relative offset for subsequent items.

This type does not support ranges (struct rte_flow_item.last).
