16.1.0.55634 19.3.v0.63786 20.0.V0.63934

Description (partial)

Symptom:
Network Adapters greater than 4 will show out of order in StarOS, in VMWare-based VMs.

VMWare 5.5 example on a UCS B series shows Network Adapters are balanced over 4 pci Bridge objects.
VM .vmx file with annotation, shows "breadth-first" sorting (by Function) provided by ESXi:
ethernet0.pciSlotNumber = "160" # F(0) B(5) D(0) => pciBridge4
ethernet1.pciSlotNumber = "192" # F(0) B(6) D(0) => pciBridge5
ethernet2.pciSlotNumber = "224" # F(0) B(7) D(0) => pciBridge6
ethernet3.pciSlotNumber = "256" # F(0) B(8) D(0) => pciBridge7
ethernet4.pciSlotNumber = "1184" # F(1) B(5) D(0) => pciBridge4
ethernet5.pciSlotNumber = "1216" # F(1) B(6) D(0) => pciBridge5
ethernet6.pciSlotNumber = "1248" # F(1) B(7) D(0) => pciBridge6
ethernet7.pciSlotNumber = "1280" # F(1) B(8) D(0) => pciBridge7
ethernet8.pciSlotNumber = "2208" # F(2) B(5) D(0) => pciBridge4
ethernet9.pciSlotNumber = "2240" # P(2) B(6) D(0) => pciBridge5

In StarOS PCI NICs will show as "Depth-first" sorted (by Bus/Slot)

Conditions:
(1) VMWare based QvPC
(2) more than 4 Network Adapters in VM
