I am not sure the comment was refering to a per socket counter here.
If the frame checksum is bad, we can not be sure the socket is OK, since the
garbaged bits could be in the tuple that identify the socket.
Maybe here we want to increment a global raw6 drop counter (well, for the
given ipv6 instance)
kfree_skb(skb);
return 0;
}

Same remark here.
