LBT looks at Ethernet traffic traversing the dvUplink, with the 75% threshold being based on the port speed. LBT does not look at the FC vmhba traffic. It is up to your CNA to either carve up the 10Gb into unique port speeds (such as 6Gb for Ethernet and 4Gb for FC / FCoE) or provide some sort of lossless flow control to FC. In either event, LBT is solely focused on the Ethernet dvUplink saturation, not the CNA saturation.
