I don't think you need the __constant_htons() here, just htons() - that's what tcp_ipv6.c does.

+static void
+ah_debug_packet(struct ip_vs_protocol *pp, const struct sk_buff *skb,
+               int offset, const char *msg)
+{
+#ifdef CONFIG_IP_VS_IPV6
+       if (skb->protocol == __constant_htons(ETH_P_IPV6))
+               ah_debug_packet_v6(pp, skb, offset, msg);
+       else
+#endif

htons()

+static void
+esp_debug_packet(struct ip_vs_protocol *pp, const struct sk_buff *skb,
+                int offset, const char *msg)
+{
+#ifdef CONFIG_IP_VS_IPV6
+       if (skb->protocol == __constant_htons(ETH_P_IPV6))
+               esp_debug_packet_v6(pp, skb, offset, msg);
+       else
+#endif

htons()

I think there's more in one of the other patches too.

So why can't you just create one ip_vs_debug_packet_v6() instead of these ah and esp ones which are identical?
