[IPSEC]: Move ip_summed zapping out of xfrm6_rcv_spi
Not every transform needs to zap ip_summed. For example, a pure tunnel mode encapsulation does not affect the hardware checksum at all. In fact, every algorithm (that needs this) other than AH6 already does its own ip_summed zapping. This patch moves the zapping into AH6 which is in line with what IPv4 does. Possible future optimisation: Checksum the data as we copy them in IPComp. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
