Follow the RFC6980 and silently ignore following IPv6 NDP messages
that had the IPv6 fragmentation header:
 o  Neighbor Solicitation
 o  Neighbor Advertisement
 o  Router Solicitation
 o  Router Advertisement
 o  Redirect

Introduce M_FRAGMENTED mbuf flag, and set it after IPv6 fragment reassembly
is completed. Then check the presence of this flag in correspondig ND6
handling routines.
