Subject: question about __udp6_lib_err usage of __udp6_lib_lookup

__udp6_lib_lookup's prototype is ...

struct sock *__udp6_lib_lookup(struct net *net,
                                      const struct in6_addr *saddr, __be16 sport,
                                      const struct in6_addr *daddr, __be16 dport,
                                      int dif, struct udp_table *udptable)

But the usage in __udp6_lib_err is...

 521         sk = __udp6_lib_lookup(dev_net(skb->dev), daddr, uh->dest,
 522                                saddr, uh->source, inet6_iif(skb), udptable);

With the source/dest addr/port arguments swapped. Is this intentional ?
