From 65a2022e89a4760f9702837e2d9d15a39a9c68a3 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Wed, 9 May 2018 20:34:25 -0700 Subject: net/ipv6: Add fib lookup stubs for use in bpf helper Add stubs to retrieve a handle to an IPv6 FIB table, fib6_get_table, a stub to do a lookup in a specific table, fib6_table_lookup, and a stub for a full route lookup. The stubs are needed for core bpf code to handle the case when the IPv6 module is not builtin. Signed-off-by: David Ahern Acked-by: David S.
