- * IP4 reassembly logic:

- * 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.
