I'm not sure, as I don't user IPSEC, but this entry from /usr/src/UPDATING
might be of use:

        The new IPsec code is now compiled in using the IPSEC option.  The
        IPSEC option now requires "device crypto" be defined in your kernel
        configuration.  The FAST_IPSEC kernel option is now deprecated.

We have recently moved from the KAME Project's IPSEC to FAST_IPSEC.
