[ Upstream commit 1158f79f82d437093aeed87d57df0548bdd68146 ]
VRF devices are the loopbacks for VRFs, and a loopback can not be
assigned to a VRF. Accordingly, the condition in ip6_pkt_drop should
be '||' not '&&'.
Fixes: 1d3fd8a10bed ("vrf: Use orig netdev to count Ip6InNoRoutes and a fresh route lookup when sending dest unreach")
