NON_FIRST_FRAGMENT_ALSO is unrelated to IKE message fragmentation as
defined by RFC7383, but defines how to handle non-first fragments on
tunnel mode payload traffic (over ESP).

strongSwan never sends this notify and ignores it. Please refer to
RFC4301 7.2 for more details about support for non-initial fragments.
