IP4 reassembly logic: One virtually reassembled flow requires a map_ip4_reass_t structure in order to keep the first-fragment port number and, optionally, cache out of sequence packets.
There are up to MAP_IP4_REASS_MAX_REASSEMBLY such structures. When in use, those structures are stored in a hash table of MAP_IP4_REASS_BUCKETS buckets. When a new structure needs to be used, it is allocated from available ones. If there is no structure available, the oldest in use is selected and used if and only if it was first allocated more than MAP_IP4_REASS_LIFETIME seconds ago. In case no structure can be allocated, the fragment is dropped.
