xfrm: Use separate low and high order bits of the sequence numbers in xfrm_skb_cb
To support IPsec extended sequence numbers, we split the output sequence numbers of xfrm_skb_cb in low and high order 32 bits and we add the high order 32 bits to the input sequence numbers. All users are updated accordingly. Signed-off-by: Steffen Klassert <steffen.klassert@secunet.com> Acked-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.
