(

table_id

)

Get or create an IPv4 fib.

Get or create an IPv4 fib with the provided table ID.

Parameters

table_id

When set to ~0, an arbitrary and unused fib ID is picked and can be retrieved with ret->table_id. Otherwise, the fib ID to be used to retrieve or create the desired fib.

Returns

A pointer to the retrieved or created fib.

The IPv4 Multicast-FIB.

FIXME

This IPv4 FIB is used by the protocol independent FIB. So directly using this APIs in client code is not encouraged. However, this IPv4 FIB can be used if all the client wants is an IPv4 prefix data-base
