[Bug 197286] Panic in IPv6 stack - 0xc0d0b1fc is in ip6_input (/usr/src/sys/netinet6/ip6_input.c:702)

--- Comment #4 from Andrey V. Elsukov <ae at FreeBSD.org> ---
r274300 is very dangerous for merging to stable/10. Can you try this patch
instead? It disables LLE operations for tunneling interfaces, and therefore
ip6_input() will go through another code path for such packets.
