Detailed Description

Warning:

EXPERIMENTAL: All functions in this file may be changed or removed without prior notice.

This API allows to do control path functions of ip4_* nodes like ip4_lookup, ip4_rewrite.

Function Documentation

int rte_node_ip4_route_add (uint32_t ip, uint8_t depth, uint16_t next_hop, enum rte_node_ip4_lookup_next next_node)

Add ipv4 route to lookup table.

Parameters:

ip IP address of route to be added.
depth Depth of the rule to be added.
next_hop Next hop id of the rule result to be added.
next_node Next node to redirect traffic to.

Returns:

0 on success, negative otherwise.

int rte_node_ip4_rewrite_add (uint16_t next_hop, uint8_t * rewrite_data, uint8_t rewrite_len, uint16_t dst_port)

Add a next hop's rewrite data.

Parameters:

next_hop Next hop id to add rewrite data to.
rewrite_data Rewrite data.
rewrite_len Length of rewrite data.
dst_port Destination port to redirect traffic to.

Returns:

0 on success, negative otherwise.

__rte_experimental int rte_node_ip4_reassembly_configure (struct rte_node_ip4_reassembly_cfg * cfg, uint16_t cnt)

Add reassembly node configuration data.

Parameters:

cfg Pointer to the configuration structure.
cnt Number of configuration structures passed.

Returns:

0 on success, negative otherwise.
