ofproto: Add support to watch controller port liveness in fast-failover group
Currently fast-failover group does not support checking liveness of controller
port (OFPP_CONTROLLER). However this feature can be useful for selecting
alternate pipeline when controller connection itself is down for e.g.
by using local DHCP server to reply for any DHCP request originating from VMs.
This patch adds the support for watching controller port liveness in fast-
failover group. Controller port is considered live when atleast one
of-connection is alive.
Example usage:
ovs-ofctl add-group br-int 'group_id=1234,type=ff,
bucket=watch_port:CONTROLLER,actions:<A>,
bucket=watch_port:1,actions:<B>
