Hi,
- The IPv6 handler for receiving packets is ipv6_rcv() in net/ipv6/ip6_input.c.
It is called by netif_receive_skb() (net/core/dev.c)
According to the documentation, the return value of netif_receive_skb() should
be NET_RX_DROP when the packet is dropped; though this return value
is usually not used (except maybe for congestion), this patch fixes the
ipv6_rcv() to return NET_RX_DROP when the packet is dropped (note that
NET_RX_DROP value **is not** 0 but 1; NET_RX_SUCCESS value is in fact	0).
