By the way, what's the point of multiple rings in corosync when we can setup
bonding or teaming on OS layer?

I remember some times ago bonding was recommended over corosync rings, because
the totem protocol on multiple rings wasn't as flexible than bonding/teaming
and multiple rings was only useful to corosync/pacemaker where bonding was
useful for all other services on the server.

...But that was before the knet era. Did it changed?
