struct rte_fib6 * rte_fib6_create | ( | const char * | name, |
int | socket_id, | ||
struct rte_fib6_conf * | conf | ||
) |
Create FIB
name | FIB name |
socket_id | NUMA socket ID for FIB table memory allocation |
conf | Structure containing the configuration |
struct rte_fib6 * rte_fib6_find_existing | ( | const char * | name | ) |
Find an existing FIB object and return a pointer to it.
name | Name of the fib object as passed to rte_fib6_create() |
void rte_fib6_free | ( | struct rte_fib6 * | fib | ) |
Free an FIB object.
fib | FIB object handle created by rte_fib6_create(). If fib is NULL, no operation is performed. |
int rte_fib6_add | ( | struct rte_fib6 * | fib, |
const uint8_t | ip[RTE_FIB6_IPV6_ADDR_SIZE], | ||
uint8_t | depth, | ||
uint64_t | next_hop | ||
) |
Add a route to the FIB.
fib | FIB object handle |
ip | IPv6 prefix address to be added to the FIB |
depth | Prefix length |
next_hop | Next hop to be added to the FIB |
int rte_fib6_delete | ( | struct rte_fib6 * | fib, |
const uint8_t | ip[RTE_FIB6_IPV6_ADDR_SIZE], | ||
uint8_t | depth | ||
) |
Delete a rule from the FIB.
fib | FIB object handle |
ip | IPv6 prefix address to be deleted from the FIB |
depth | Prefix length |
int rte_fib6_lookup_bulk | ( | struct rte_fib6 * | fib, |
uint8_t | ips[][RTE_FIB6_IPV6_ADDR_SIZE], | ||
uint64_t * | next_hops, | ||
int | n | ||
) |
Lookup multiple IP addresses in the FIB.
fib | FIB object handle |
ips | Array of IPv6s to be looked up in the FIB |
next_hops | Next hop of the most specific rule found for IP. This is an array of eight byte values. If the lookup for the given IP failed, then corresponding element would contain default nexthop value configured for a FIB. |
n | Number of elements in ips (and next_hops) array to lookup. |
void * rte_fib6_get_dp | ( | struct rte_fib6 * | fib | ) |
Get pointer to the dataplane specific struct
fib | FIB6 object handle |

enum rte_fib6_lookup_type | type | ||
) |
Set lookup function based on type
