* - Add MCAP. Limited Multicast exists only to 224.0.0.1 and 224.0.0.2.
*
* Non-RFC 2734 related:
* - Fix bug related to fragmented broadcast datagrams
* - Handle fragmented skb's coming from the networking layer.
* - Move generic GASP reception to core 1394 code
* - Convert kmalloc/kfree for link fragments to use kmem_cache_* instead
* - Stability improvements
