# rte\_swx\_ctl\_table\_match\_field\_info(3)

## NAME

rte\_swx\_ctl\_table\_match\_field\_info

## SYNOPSIS

`#include <rte_swx_ctl.h>`

### Data Fields

enum **rte\_swx\_table\_match\_type** **match\_type**\
 int **is\_header**\
 uint32\_t **n\_bits**\
 uint32\_t **offset**\

## Detailed Description

Table match field info.

If (n\_bits, offset) are known for all the match fields of the table, then the table (key\_offset, key\_size, key\_mask0) can be computed.
