-Prints to the console the sets of port groups maintained by datapath
-\fIdp\fR. Ordinarily there are at least 2 port groups in a datapath
-that \fBovs\-openflowd\fR or \fBovs\-vswitch\fR is controlling: group
-0 contains
-all ports except those disabled by STP, and group 1 contains all
-ports. Additional or different groups might be used in the future.
