ipv6: Only create RTF_CACHE routes after encountering pmtu exception This patch creates a RTF_CACHE routes only after encountering a pmtu exception. After ip6_rt_update_pmtu() has inserted the RTF_CACHE route to the fib6 tree, the rt->rt6i_node->fn_sernum is bumped which will fail the ip6_dst_check() and trigger a relookup.
