Log: Merge r281536 pf: Fix forwarding detection If the direction is not PF_OUT we can never be forwarding. Some input packets have rcvif != ifp (looped back packets), which lead us to ip6_forward() inbound packets, causing panics. Equally, we need to ensure that packets were really received and not locally generated before trying to ip6_forward() them.
