tipc: add InfiniBand media type
Add InfiniBand media type based on the ethernet media type. The only real difference is that in case of InfiniBand, we need the entire 20 bytes of space reserved for media addresses, so the TIPC media type ID is not explicitly stored in the packet payload.

Setting this to a smaller value saves some memory,
setting it to higher allows for more ports.
