-The original packet in ipmr_cache_report() may be queued and then forwarded
-with ip_mr_forward(). This last function has the assumption that the skb
-dst is set.
-
-After the below commit, the skb dst is dropped by ipv4_pktinfo_prepare(),
-which causes the oops.
-
-Fixes: bb7403655b3c ("ipmr: support IP_PKTINFO on cache report IGMP msg")
