From 71df5777aaaeff673c242a49b945b1b96fe81718 Mon Sep 17 00:00:00 2001 From: David Ahern Date: Fri, 5 Apr 2019 16:30:25 -0700 Subject: ipv6: Add neighbor helpers that use the ipv6 stub Add ipv6 helpers to handle ndisc references via the stub. Update bpf_ipv6_fib_lookup to use __ipv6_neigh_lookup_noref_stub instead of the open code ___neigh_lookup_noref with the stub.
