The vrf situation does not apply here - at least not yet. Maybe I am missing something but ping_v6_sendmsg does not support IPV6_PKTINFO, so the potential oif override of sk_bound_dev_if is not there. I'll add this to the to-do list -- make IPv6 compatible with IPv4 wrt PKTINFO and then add in the VRF fix up discussed.
