Both these CNAs are single Chip with 4 PCI functions presented to the Host side. As the external interface there will be 2 FCoE SFP+ ports. Ethernet-0 and FC-2 PCI functions goes to FCoE-0 port. Ethernet-1 and FC-3 PCI functions goes to FCoE-1 port.
Here is the Host side view of the Qlogic and Emulex HBAs /devices/pci at 500/pci at 0/pci at d/ethernet at 0 /devices/pci at 500/pci at 0/pci at d/ethernet at 0,1 /devices/pci at 500/pci at 0/pci at d/QLGC,qlc at 0,2 /devices/pci at 500/pci at 0/pci at d/QLGC,qlc at 0,3 /devices/pci at 7c0/pci at 0/pci at 9/ethernet at 0 /devices/pci at 7c0/pci at 0/pci at 9/ethernet at 0,1 /devices/pci at 7c0/pci at 0/pci at 9/fibre-channel at 0,2 /devices/pci at 7c0/pci at 0/pci at 9/fibre-channel at 0,3 With this, I think all questions are answered.
