there are there nodes, use "knet_link_get_link_list" to get num_links, use "knet_link_get_status" to get link status

here is the ip addr
node1(10.67.19.168, 10.67.18.84, 10.67.18.52)
node2(10.67.19.210, 10.67.18.53, 10.67.18.88)
node3(10.67.18.247, 10.67.19.238, 10.67.19.178)

I disabled "10.67.19.168" first, then corosync on node1 switched to "10.67.18.84", and when I re-enabled "10.67.19.168", corosync switched back to ""10.67.19.168", these are expected.

but when I debug corosync: totemknet_ifaces_get(), here is the link status of knet.

node 1:
num_links = 1
10.67.19.168 -> 10.67.19.168

node 2:
num_links = 3
10.67.19.168 -> 10.67.19.210
10.67.18.84  -> 10.67.18.53
10.67.18.52  -> 10.67.18.88

node 3:
num_links = 3
10.67.19.168 -> 10.67.18.247
10.67.18.84  -> 10.67.19.238
10.67.18.52  -> 10.67.19.178

what I want to say is the link normal? shouldn't and in this way, not all elements can be updated, this is why there are two 'n' in the output of 'corosync-cfgtool -s -b'
