Description of problem:
From the man page:
 -i, --interface <ethX>
 Show the information of the FCoE instances created at <ethX>.  If <ethX> is not specified the command will show the information of all the FCoE instances created on the system.

 -t, --target <ethX>
 Show  the  information  of all the discovered targets from the FCoE instances created at <ethX>.  If <ethX> is not specified the command will show the information of all the discovered targets from all the FCoE instances created.


The long options indeed need parameters and do not show info of all the FCoE instances created on the system
