ipv6: Change skb->data before using icmpv6_notify() to propagate redirect
[ Upstream commit 7801a085efab5f1d7cc54fa1f80b0c69b457db68 ]
In function ndisc_redirect_rcv(), the skb->data points to the transport
header, but function icmpv6_notify() need the skb->data points to the
inner IP packet. So before using icmpv6_notify() to propagate redirect,
change skb->data to point the inner IP packet that triggered the sending
of the Redirect, and introduce struct rd_msg to make it easy.
