Subject: [PATCH iproute2 net-next v1 4/7] tipc: add link monitor summary
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
