Description (partial)

Some fragmented TCP/UDP traffic may not be encrypted or may be encrypted with the wrong key.

When the crypto policy is specified such that the IP source and destination addresses and IP
protocol are easily matched, and with L4 port information, the fragments which do not have L4
information (for example, the non-first fragment) may be wrongly matched to outgoing encryption
policy. The fragments may go clear or may be encrypted using wrong key.
