* TRILL instance structure, one for each TRILL instance running in
* support of a bridge instance. Members ti_bridgename and ti_binst
* refer to the specific bridge instance. The bridge instance in
* question must be online before we can support and rely on it.
* We rely on the bridge instance for TRILL sockets to transmit and
* receive TRILL packets. Each TRILL instance holds the TRILL
* forwarding and nick database in ti_nodes. trill_inst_rwlock
* protects changes to the TRILL instances list. Within each TRILL
* instance the ti_rwlock protects changes to the structure. A refcount
* (ti_refs) helps in destroying the TRILL instance when all TRILL
* sockets part of the instance are shutdown.

* is the designated forwarder on the link for a particular VLAN.
* A refcount (ts_refs) ensures the last consumer (TRILL module
* or the IS-IS daemon) destroys the socket.
