This object holds the raw 2-byte IEEE 802.5 Token Ring Routing Control field for one manually configured source-route entry, encoding the routing type, direction, and hop information defined by the source-routing bridge standard. An admin managing legacy Token Ring bridges reads and sets this alongside the route descriptor object to define exactly how frames are source-routed to a particular remote ring. For example, a specific 2-byte value here might indicate a specific-route frame spanning three ring-bridge hops.
