Hi,

recently we did some IP forwarding tests and the GENERIC kernel is
several times faster than GENERIC+IPSEC. Even when IPSEC has no SA.

I didn't do test on vanilla kernel, but our kernel is able forward
IPv4/IPv6 on rate close to 8.6 Mpps. The same kernel compiled with IPSEC
can forward only 180 kpps. I think this problem should be solved before
enabling it in GENERIC.
