xfrm6: handling fragment
RFC4301 Section 7.1 says:
"7.1. Tunnel Mode SAs that Carry Initial and Non-Initial Fragments
All implementations MUST support tunnel mode SAs that are configured
to pass traffic without regard to port field (or ICMP type/code or
Mobility Header type) values. If the SA will carry traffic for
specified protocols, the selector set for the SA MUST specify the
port fields (or ICMP type/code or Mobility Header type) as ANY. An
SA defined in this fashion will carry all traffic including initial
and non-initial fragments for the indicated Local/Remote addresses
and specified Next Layer protocol(s)."
But for IPv6, fragment is treated as a protocol. This change catches
protocol transported in fragmented packet. In IPv4, there is no
problem.
