Hi,
According to this document you don't need the advanced license to run FCOE. You just need the FCOE license for the F3 module that runs FCOE.
Each F Series module that runs FCoE requires an FCoE license. FCoE enabled in a nondefault VDC does not require the Advanced Services License. By default, FCoE does not require an additional VDC and is enabled in the storage VDC. For a complete explanation of the Cisco NX-OS licensing scheme and how to obtain and apply licenses, see the Cisco

According to table-2 in this link, you have the correct license for FCOE
