[IPSEC]: Fix bogus usage of u64 on input sequence number
Al Viro spotted a bogus use of u64 on the input sequence number which is big-endian. This patch fixes it by giving the input sequence number its own member in the xfrm_skb_cb structure. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
