[Cluster-devel] [PATCH] rgmanager: Add IP "interface" parameter



This patch adds an "interface" parameter for IP resources. The
interface must already be configured and active. This parameter
should be used only when at least two active interfaces have IP
addresses on the same subnet and it's necessary to specify which
particular interface should be used.
