The monitor summary command prints the basic attributes
specific to the local node.
A sample usage is shown below:
$ tipc link monitor summary
bearer eth:data0
table_generation 15
cluster_size 8
algorithm overlapping-ring
bearer eth:data1
table_generation 15
cluster_size 8
algorithm overlapping-ring
$ tipc link monitor summary -h
Usage: tipc monitor summary

v2: - for keys containing multiple strings, use "_" as string delimiter. This
pattern is used in rest of iproute2 package (ex "ip ntable").
- replace state with current algorithm in output.
